I am using Dual CPU AMD Opteron2378 with Sata harddrive with 32MB cache for
Samba File Server. I have installed CentOS5.3 64bit on it.
Currently 80 users are using that server at same time. All users are using
OpenOffice, Write, Pagemaker on their desktop machines and they work on
server directly. It gives good performance.
There are 10 users who use CorelDraw & Photoshop for their work and they
work locally. Now I put their data on server told them to work on Server
But it reduced their working speed by 50% than locally and on server DiskIOs
also got increased. So then I disconnected all users and only provide access
to those 10 users. So they are working on the server dedicatedly but still
performance was slower than local.
Query : How can I increase Performance for them ? what configuration I
should have to serve those users as a File Server ?
Note: All network cables are CAT6 and switches are of 100MBs.
Query: If HDD is the weakpoint then, will SAS hdd be helpful under these
circumstances? I heard that SAS HDD are faster that Sata. They have 2
catagories 3Gb/s and 6 Gb/s. Even we can get PCIxpress card for SAS ports
from Promise. Can Linux supports these cards?
Thanks in advance
