Com.sap.ip.bi.web.portal.integration.launcher slow in Portal

Question

Hi experts,
com.sap.ip.bi.web.portal.integration.launcher is consistently showing as one of the slowest-running in our NW2004s SP16 Portal (non-Federated).  Even the report variable screen is slow to load especially on first-time access. E.g., 31.8 seconds first time, 5.9 seconds second access in same session.
But what is curious is that it sometimes the variable screen load time goes as low as 350ms if you keep trying within the same session.
We've done the obvious - patching the BI Web App components, tuning the portal & Java runtime, checking the JCOs, load-balancing, tweaked the BI backend... but without being able to impact the performance of this application substantially.
So I would value any suggestions for improvement!  Any tables we can cache?  Any SAP Notes to shed some light on this area?  Any Portal settings to tweak?
Thanks, Marc

Hi Marc,
Slow point are to com.sap.ip.bi.web.portal.integration.launcher and
JCO connection. Would you please check CPIC_MAX_CONV in SAP Note 314530?
-Regarding of BI java on Web performance, would you please check the
SAP Note 1022930?
SAP Note 1025307 is a summary notes for performance on Web.
Do you use antivirus software with a javascript  scanner, but still would you please also check the SAP Note 983066 because sometime this also may responsible for slow performance.
SAP Note 948158:  Performance problems/measuring BI Java Web runtime
One more thing would like to highlight:
In first acess it's slow because OLAP cache was not in use, but after the first execution it's loading the variable from the cache so it's comperatively fast then the previous acess.
Let me know, incase any confusion..
Thank you,
