Actually the image size is arround 100KB each. The server is running in 250Mbps traffic.
I already described the disk I'm using is scsi 15K RPM in raid 0

But if those 5,000 req/s each hit a different 1mb image then you need to
read 5gb of data from you storage which if your storage is just a plain old
sata disk is going to be a huge problem.

Unfortunately Indo Php is not providing nearly enough information to give
any sort of advice. If he is lucky then putting lots of ram in the machine
for pagecache can help here if the cache hit ratio is good but if it is not
then he probably has to distribute the I/O across more spindles and go for
a raid with lots of disks.

Regards,
Dennis
