Systat disk read numbers

My customer added PAM cards .My customer is noticing that disk read KB/s and network out KB/s are about the same on sysstat as before , even when PAM shows significant savings for disk reads – are the disk reads reflecting reads from disk _and_ PAM (hence the disk read KB/s being higher than network even with PAM on), or is it that the disk reads would have been higher?

Any repsonse is greatly appretiated.

Re: Systat disk read numbers

In what mode is the PAM being used? meta only, low_pri or mixed?

Re: Systat disk read numbers

PAM card is being used in Normal mode, which should be mixed IIRC.
