Hi Arnaud,
Take a look on "TSM performance Tuning Guide".
On that manual, you could find the following:
"Recommendations for AIX, HP, Sun, NT, OS/2 Servers
System Memory (MB) Recommended BuffPoolSize(MB) RBufferPoolSize (KB)
32 2
2048
48 3

14336
160 20
20480
256 32

subject: Sizing of Bufpoolsize
> Hi *SM fellows,
>
> I'm running TSM 4.2.3.1 on an AIX 4.3.3 system (IBM 6h0) with 2 GB ram, the
> db size is 21 GB, 75 % used, the logpool size is 12 GB. Since 3 weeks (when
> we upgraded from 4.2.1.15), I get massive performance degradation : expire
> inventory takes ages (approx 20 hours) to go through 9 million objects, and
> cache hit ratio is between 94 and 96 %. 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.
> Could you please share your bufpoolsize settings with me, if working in the
> same kind of environment, or give me some advice for tuning the server ?
> Thanks in advance !
