No, not quite.
TSM database size is 150 GB.
Server RAM size 32 GB.
Summary:
BUFPOOLSIZE when it is too large, which my guess is the point at which a
search through that much memory takes longer than a disk read.

We are about to upgrade to a 6 x 750 MHZ from a 4 x 450 MHZ. At that
point, I will consider doing more bufferpool. The problem is the buffer
processing does use some CPU resources, especially
), so I
may run my bufferpool up to a gigabyte.

I tried to increase my bufpoolsize from 151 MB to 400 in several 100 GB steps without
seeing any improvement, and the system is now heavily paging.

It depends on youre amount of system memmory and can vary a bit.

you are doing.
