By the way, how much RAM does the box have available?
tmpfs in Solaris is backed by virtual memory.

So basically you're comparing linux + ext3/4 performance with solaris

Hi,
I'm migrating a webserver(apache+php) from RHEL to solaris. During the
stress testing comparison, I found under the same session number of client
request, CPU% is ~70% on RHEL while CPU% is full on solaris.
After some investigation, zfs root lock emerges as a major doubtful point.
Firstly,
I have a USB disk with opensolaris200906 installed.
I'm using it to test OS on the different boxes.
Recently(B109, B110, B111) I run into a weird problem from time
to time.

for windows we use ghost to backup system and recovery.

Do you ever do installgrub to the slice, and boot up from the

It should be
