Hi everybody,
I have some doubts about sharedmemory and work_mem.
I have a server:
64 GB RAM
2 processors 4 cores each one intel xeon 3 Ghz
expecting 300 users in the same time
So, I put in sharedbuffers the same size my two biggest tables, which
are the most read too. 11 GB + 4 GB. total shared buffers = 15 GB
After that I put 100 MB to each expected user, 300 * 100 MB = 30 GB
So, I used only 30 GB + 15GB = 45 GB total RAM
My doubt is, can I use more RAM for shared buffers? about 30 GB (50% of
total RAM)?
What is the max shared buffers I can use? How can I calculate that?
Thanks,
Waldomiro.
