&lt;p&gt;I think this is really good to point out because when you are doing large file copies using anything with Buffered I/O, you can actually exhaust your resoruces. &lt;/p&gt;
&lt;p&gt;Buffered I/O will consume Paged Pool (1 KB of paged pool is required for each megabyte MB of file size that is opened for buffered I/O) &lt;/p&gt;
&lt;p&gt;So the Bigger your File Copy, The more Paged Pool you will consume and eventually your Copy might fail if your resource runs out before your copy Finishes. &lt;/p&gt;
&lt;p&gt;Thats why its good to use tools such as ESEUTIL that don't utilize CopyFile or CopyFileEx for large file copies. &lt;/p&gt;</description></item><item><title>re: Slow Large File Copy Issues</title><link>http://blogs.technet.com/askperf/archive/2007/05/08/slow-large-file-copy-issues.aspx#931076</link><pubDate>Fri, 11 May 2007 16:06:46 GMT</pubDate><guid isPermaLink="false">d5e57398-b9ef-4490-9955-07cbb4e4a80d:931076</guid><dc:creator>Rex2002</dc:creator><description>&lt;p&gt;I test it for BKF files... 2Gb aprox.&lt;/p&gt;

&lt;p&gt;Using copy, I got about 5MB/sec writes over gigabit. &amp;nbsp;Server computer was essentially useless until the copy completed.&lt;/p&gt;
&lt;p&gt;Using eseutil, I get about *40*MB/sec! &amp;nbsp; &amp;nbsp;&lt;/p&gt;
&lt;p&gt;I have been searching for the cause of this issue for DAYS and finally stumbled on your post. &amp;nbsp;I fought with the gigabit network card, and system cache tweaking, all to no avail. &amp;nbsp;&lt;/p&gt;
&lt;p&gt;Computer is still pretty bogged down during the transfer. &amp;nbsp;The system cache jumps to 750MB (out of the system's 1GB) usage which is the probable culprit. &amp;nbsp;But now it takes less than 1/8th the time to move the data, so the whole situation is a lot more tolerable. &amp;nbsp;I eventually figured out that the problem only was with a network file copy and not a local transfer. &lt;/p&gt;</description></item><item><title>re: Slow Large File Copy Issues</title><link>http://blogs.technet.com/askperf/archive/2007/05/08/slow-large-file-copy-issues.aspx#1684245</link><pubDate>Thu, 02 Aug 2007 22:27:59 GMT</pubDate><guid isPermaLink="false">d5e57398-b9ef-4490-9955-07cbb4e4a80d:1684245</guid><dc:creator>Magnus Rasmussen</dc:creator><description>&lt;p&gt;Any answer from microsoft on this issue?

&lt;p&gt;Open Programs &amp;amp; Features&lt;/p&gt;
&lt;p&gt;Select Turn Windows Features On or Off&lt;/p&gt;
&lt;p&gt;De-select Remote Differential Compression&lt;/p&gt;
&lt;p&gt;Select OK&lt;/p&gt;
&lt;p&gt;It will take several minutes for this to be de-activated.&lt;/p&gt;
&lt;p&gt;Reboot to be sure it takes.&lt;/p&gt;

The file copy gets to about 70% and then the RAID controller goes all wonky and basically disconnects from the system until the next reboot. We then need to add another drive to the array, rebuild the drive and then re-add the supposed bad hard drive back into the array. In other words, &amp;nbsp;the drives are fine; it's the controller that gives out.&lt;/p&gt;
&lt;p&gt;I am concluding that the RAID controller that I am trying to use is buggy. I have tried another controller from the same manufacturer with the same results.&lt;/p&gt;
&lt;p&gt;Eseutil is obviously copying the file so fast that it is triggering a bug in the controller. Eseutil has helped me identify this bug. Jury is still out as to whether this will happen when I use Robocopy or another file copy program.&lt;/p&gt;

&lt;p&gt;Any advice???&lt;/p&gt;</description></item><item><title>re: Slow Large File Copy Issues</title><link>http://blogs.technet.com/askperf/archive/2007/05/08/slow-large-file-copy-issues.aspx#3075085</link><pubDate>Fri, 20 Jun 2008 19:47:20 GMT</pubDate><guid isPermaLink="false">d5e57398-b9ef-4490-9955-07cbb4e4a80d:3075085</guid><dc:creator>Mark Pleasance</dc:creator><description>&lt;p&gt;Hi Everyone,&lt;/p&gt;
&lt;p&gt;Using robocopy (XP010) for a dozen MS SQL2000 DB backup files (and logs) . . . ~50GB-150GB (pending on what time of the month it is . . . ;0) in a batch file mapping drive letters to remote shared folders.&lt;/p&gt;
&lt;p&gt;During the copy of the largest single file I encountered the error &amp;quot;ERROR 1130 (0x0000046A) Copying File &amp;lt;insert file name here&amp;gt; Not enough server storage is available to process this command. &amp;nbsp;Waiting 30 seconds... Retrying...&amp;quot;&lt;/p&gt;
&lt;p&gt;Tried the same copy with windows explorer . . . One file at a time would copy OK . . . but the &amp;quot;not enough server storage&amp;quot; error would occur if I tried copying ALL the files at once.&lt;/p&gt;
&lt;p&gt;We fixed the issue with simple configuration / tuning changes . . . here's the list we used . . . &lt;/p&gt;
&lt;p&gt;On the receiving (Windows 2003) server . . . &lt;/p&gt;
&lt;p&gt;1.) &amp;nbsp;latest greatest service pack / updates&lt;/p&gt;
&lt;p&gt;2.) &amp;nbsp;Local area connetion properties -&amp;gt; File and Printer sharing for Microsoft networks (properties) -&amp;gt; changed &amp;quot;Server Optimization&amp;quot; to &amp;quot;Maximize data throughput for file sharing&amp;quot; (was set to Net Apps)&lt;/p&gt;
&lt;p&gt;3.) &amp;nbsp;System Properties -&amp;gt; Advanced Tab -&amp;gt; Advanced Tab - Processor scheduling - Adjust for best performance of: Change to &amp;quot;Background services&amp;quot; (was set to &amp;quot;Programs&amp;quot;)&lt;/p&gt;
&lt;p&gt;4.) Set swap file to recomended parameters / size&lt;/p&gt;
&lt;p&gt;5.) Reboot . . . &lt;/p&gt;
&lt;p&gt;6.) Test, Test, Test, Test . . . &lt;/p&gt;
&lt;p&gt;Hopefully someone finds this information usefull . . .&lt;/p&gt;

&lt;p&gt;ESEUTIL works great for copying 10gb+ files on our network. It's much faster that robocopy, xcopy, teracopy etc.&lt;/p&gt;
&lt;p&gt;I didn't have access to an exchange server so I downloaded an Exchange service pack, ran the exe with the -x option to unpack it, and then searched for and found eseutil.exe and ess.dll.&lt;/p&gt;
&lt;p&gt;Here's a short script that I'm using to copy files I have with a .bku extension. Oviously this can be easily modified to fit your needs.&lt;/p&gt;
&lt;p&gt;@echo off&lt;/p&gt;
&lt;p&gt;set DESTDIR=\\servername\sharename&lt;/p&gt;
&lt;p&gt;set SRCDIR=f:\backupfiles&lt;/p&gt;
&lt;p&gt;for %%f in (%SRCDIR%\*.bku) do (&lt;/p&gt;
&lt;p&gt; &amp;nbsp;del %DESTDIR%\%%~nxf&lt;/p&gt;
&lt;p&gt; &amp;nbsp;ESEUTIL /Y %%f /D %DESTDIR%\%%~nxf&lt;/p&gt;

&lt;p&gt;The question I have is that I cannot get the throughput to the max of the network. &amp;nbsp;I am using gigabit between servers in their own dedicated vlan so there is no traffic on the line. &amp;nbsp;The max I can push the network is about 45%. &amp;nbsp;Is there a way to optimize this to get it to copy even faster or is this a limitation of eseutil.&lt;/p&gt;

&lt;p&gt;WinVista - even w/SP1, any type of file operations appear to dog it... Vista quite often doesn't respond to file operations properly... this is small/large, you name it... any further fixes post SP1 ? (I've also disabled Differential Compression, made a world of difference for a little while, but still not the performance of XP or Win2003...)... Vista just plain sucks! If it wasn't that I was running it for Media Center, I'd say chunck it... odd part is, if you reload the OS, it runs fine, until you try to load just a few little apps, and actually try to make it a &amp;quot;working system&amp;quot; ... all virus scanned, and same files come from other running system... I know os's extremely well, and haven't been able to locate this one yet...&lt;/p&gt;
&lt;p&gt;2nd one on Win2003 - issue w/renaming a directory, moving it, etc... it has about 100,000 files in it (yes, they have to be there)... win2003 hangs for 5-10 mins on a dual proc quad core enterprise server.... only thing I've been able to locate so far to help I have 1 directory w/about 35,000 files in it... if I move everything excluding that dir, it's done in seconds... if I move that dir in it's entirety, it's quick, if I move it as one (~30,000 files or more at a time), it hangs... same if I move more than ~30,000 files in multiple dirs... some type of MS limitation or caching issue? &lt;/p&gt;</description></item><item><title>re: Slow Large File Copy Issues</title><link>http://blogs.technet.com/askperf/archive/2007/05/08/slow-large-file-copy-issues.aspx#3171665</link><pubDate>Sun, 21 Dec 2008 03:37:15 GMT</pubDate><guid isPermaLink="false">d5e57398-b9ef-4490-9955-07cbb4e4a80d:3171665</guid><dc:creator>Dantek</dc:creator><description>&lt;p&gt;Great stuff with ESEUTIL.

&lt;p&gt;ESLUTIL appears to be changing the file size at the destination and as such the image backup is useless and fails when you try to use it.&lt;/p&gt;
&lt;p&gt;It appears to be adding to the initial file size....but no errors are generated when copying takes place. &amp;nbsp;You can see immediately that the file size does not match each time this is done!!!&lt;/p&gt;

&lt;p&gt; &amp;nbsp; Presently I write an application to copy the hard disk partition to another partition..So I wanna get it fast compare to the speed of CopyFile() function in Windows. &lt;/p&gt;
&lt;p&gt;I have tried so many methods,,,all leads to failure....&lt;/p&gt;
&lt;p&gt;Hii&lt;/p&gt;
&lt;p&gt;I wanna copy an NTFs partition to another partition of same type and same size.And I tried with windows function&lt;/p&gt;
&lt;p&gt;Copyfile() and it worked but slow speed is a problem.Then I did with readfile() and WriteFile() instead of Copyfile() again speed is a problem.&lt;/p&gt;
&lt;p&gt;How can I get a better speed...??&lt;/p&gt;
&lt;p&gt;I did the same operation in kernel mode and getting slow performance using zwCreatefile() ,zwReadfile() &amp;amp; zwWriteFile()...&lt;/p&gt;
&lt;p&gt;How can I get a better speed .....?&lt;/p&gt;
&lt;p&gt;I want to copy a hard disk partition into another partition. My source and destination partitions are of NTFs and same size. For that purpose first I did by copying all sectors and it is working, But I wanna copy only used sectors…&lt;/p&gt;
&lt;p&gt;Then I find the used clusters by reading the FSCTL_VOLUME_BITMAP. But this one also a slow one ..I want to get better speed. And I tried to get the used clusters by using the FSCTL_GET_RETEIVAL_POINTER also. But it's a slow one.....&lt;/p&gt;
&lt;p&gt;At last I tried the windows API CopyFile() also…But everything gives a slow performance…&lt;/p&gt;
&lt;p&gt;I know fundamentally Kernel mode(ring 0) is slower than User mode in speed ,(even if ring 0 can access Hardware directly).....&lt;/p&gt;
&lt;p&gt;Apart them these I tried also Asynchronous operation by setting OVERLAPPED flag in CreateFile.... getting small improvement....&lt;/p&gt;
&lt;p&gt;And I've taken snapshot (Volume shadow copy)of the Volume and copied the files using Hobo copy method...but everything gives the same speed.....&lt;/p&gt;
&lt;p&gt;Any idea to help...&lt;/p&gt;
&lt;p&gt;I have used the Software Acronis Disk director suite .I exclaimed after finding it's speed......!!!!!!&lt;/p&gt;
&lt;p&gt;Any idea to help me...to get a good speed.......???&lt;/p&gt;
&lt;p&gt;Any links to the white papers related to this section...???&lt;/p&gt;
&lt;p&gt;-----------------------&lt;/p&gt;
&lt;p&gt; &amp;nbsp;Thanking you&lt;/p&gt;
