Is there any changes in Domino 8.0.1 compared to Domino 7.0.x regarding DIIOP performance?
The DIIOP task uses a lot of RAM and CPU in Domino 7.0.x.
Subject: I don’t think there are major things but…
do you already use a connection pooling framework to access DIIOP sessions ?
We built one (using apache common pool) and it can really boost performances session opening / closing is really expensive.
Subject: DIIOP uses 40% CPU power
We are using DIIOP on a iSeries (V5R4) and that task uses 40%of the CPU power. That is more than any running SAP system!!!
IBM has just told us that they won’t solve this issue on iSeries and recomment us to use a Windows server to the DIIOP data transfer.
I don’t know what framework is used to access DIIOP. It not our own application that uses it. It’s DME (PIM sync).
