Got a 2008 server in production , which currently has "one" disc. (Actually a SAS array, presented as a single disc to the OS.)
This "disc" is partitioned into a few sections, with some free space left over.
Someone has the app on the server running off of the C: partition. A bit of lag was sensed and we presumed that the OS tasks might be slightly affecting the app performance.
So, we took some free space and created a logical volume there. Put the app onto the logical volume, by itself. Now the app lags slightly more.
Anything we can do to address this slight lag for some performance, disc-wise? (besides putting in another separate array and moving the app there?)
