Guest aengus Posted August 20, 2007 Posted August 20, 2007 Hi, A drive on a Windows 2003 server is compressed and a user is reading and writing files on that drive over the LAN from his desktop computer. Which computer is doing the processing associated with compressing and decompressing the data? Is it the server, or the user's desktop machine? Thanks, Aengus.

Guest Coraleigh Miller Posted August 20, 2007 Posted August 20, 2007 Re: CPU load due to having drives on a server compressed. Hi aengus, The server is doing all the work. The user may notice a speed decrease while opening or saving files on a compressed drive but this is due to the server and network bandwidth. http://support.microsoft.com/kb/251186 Coraleigh Miller "aengus" <aengus@gmail.com> wrote in message news:1187578481.953393.152810@e9g2000prf.googlegroups.com... > Hi, > > A drive on a Windows 2003 server is compressed and a user is reading > and writing files on that drive over the LAN from his desktop > computer.

Guest Coraleigh Miller Posted August 20, 2007 Posted August 20, 2007 Re: CPU load due to having drives on a server compressed. Hi again aengus, I defer to Dave Patrick on this one. :-) I just ran perfmon on my server and client and setup a quick test to see what happened and sure enough my client's CPU and IO spiked while the file server stayed level. Thanks Dave!

Guest aengus Posted August 20, 2007 Posted August 20, 2007 Re: CPU load due to having drives on a server compressed. There's two conflicting answers! The KB article seems to indicate that the server is doing all the work. Thanks, Aengus.

Guest aengus Posted August 20, 2007 Posted August 20, 2007 Re: CPU load due to having drives on a server compressed. Ok, fair enough... But the KB article _does_ suggest differently doesn't it? In the case of decompression, the article says "Compressed files are also expanded before copying over the network", how could the user's computer do the work in this case? Cheers, Aengus.

Guest Coraleigh Miller Posted August 20, 2007 Posted August 20, 2007 Re: CPU load due to having drives on a server compressed. It does indeed! Out of my respect for Dave Patrick however I decided to perform my own little test as well as gave a closer inspection to the article and it doesnt actually cite our situation exactly. Try running a perfmon test on your server and client after hours to see what you come up with.

Guest Dave Patrick Posted August 20, 2007 Posted August 20, 2007 Re: CPU load due to having drives on a server compressed. Thank you for the compliment. I also read your article with interest. I don't see how/why the server would handle the request for compression/decompression. I'll be interested to see aengus's test result as well. -- Regards, Dave Patrick ....Please no email replies - reply in newsgroup.

Guest aengus Posted August 20, 2007 Posted August 20, 2007 Re: CPU load due to having drives on a server compressed. Now that I know what MVP stands for, it seems Dave Patrick is one to be trusted on this issue alright! I'll run a perfmon at some point just to have a look, but I consider the question answered now. Thanks again, Aengus. On Aug 20, 2:08 pm, "Coraleigh Miller" <CoraleighMil...@yahoo.com> wrote: > It does indeed!

Guest aengus Posted August 20, 2007 Posted August 20, 2007 Re: CPU load due to having drives on a server compressed. I did a quick test. During the copying of files from the server to my local machine, the only noticeable increase in CPU usage was on the local machine. When copying files to the server, there was a similar increase in local machine CPU usage, but this seemed to be accompanied by a small increase in server CPU usage. Aengus.
