Hi All,

I hope this time somebody will answer my question here:

For each jdbc connection, postmaster starts a process that takes 10M.

Is there a way to tune this into a smaller size ??

What's the impact of reducing the process size ??

thanks,
kathy

A lot of that (program text, shared buffers etc) is shared between
backends. What's the actual unshared space taken up by each backend?

Run top and look at the SIZE and SHARE settings.

If size is 10M and share is 9.9M, then no biggie, as the delta is only
0.1M
