Hi All,

I am replying to my last email. Apologies if this cause any problems.

Please see the Disk performance below. Looks to me there is no issue on the
Disk IO.

Right now I am using CentOS 5.5 32 bit and kernel 2.6.18-194.26.1.el5PAE #1
SMP . I could not find any other way to figure out what is causing this
problem. is it a good idea to use CentOS 64 bit ?
