I would like to see the impact of different page sizes on the performance of
multi-threaded applications. However, the pagesize -a command is producing only
3 possible page sizes including the default 4Kb on my AMD machine (shown
below). Are these only page sizes I can use? (or) Is there anyway I can use
more than these?
kish...@opensolaris:~$ pagesize -a

Hi,
x86 hardware typically only has a few page size options. You might want
to look at using cputrack/cpustat/performance analyzer to see if your
application is experiencing large numbers of TLB misses. If this is the
case, changing the page size may reduce them.

Darryl.
