Hi,
I'm currently testing performance with and without huge pages. Documentation
says that in order to estimate the number of huge pages needed one should
check the postmaster's VmPeak value. I wonder if it's only postmaster memory
usage what's matters? Or I could get better estimation from the most memory
intensive postgres process - not necessarly postmaster? I'm using following
command to check it:
for i in $(ps -ef | grep postgres|awk '{print $2}'); do grep ^VmPeak
/proc/${i}/status|awk '{print $2}' >> log; done; sort -n -r log | head -1
I'm asking because some other process takes 606788kB while postmaster only
280444kB.
