Subject: TCP performance issues at AIX 5.2?

I have a TSM 5.1.6.3 server on AIX 5.2.0.0 and the TSM client and TDP
Informix are on the same system. When I use COMMMETHOD TCPIP  with
TCPSERVERADDRESS 127.0.0.1 between the client and server I get some very
strange results. If the data is going to disk storagepool then I see good
performance. If the data is going direct to LTO tape (SCSI attached) then I
see 15-sec RecvW times between blocks of data. If I do the same thing with a
client on a different server over TCPIP, then I see good performance no
matter where the data goes.

If I change the COMMMETHOD to SHAREDMEM, then I get great results. I am
using TDP Informix and I was able to backup a 40GB database direct to LTO
tape in 16-minutes. The TSM API that came with the TDP Informix agent didn't
support SHAREDMEM, so I upgraded to the 5.1.6.0 API change to SHAREDMEM and
things took off.

Has anyone seen performance issues with TSM and AIX 5.2.0.0??


TIA,
