Does anyone have hard evidence of the performance problems? I have suspicions but I'm not sure that we have problems.

Thanks.

Hi Francis
Check the following from the MS support site...
BUG: IIS 6.0 is slower than IIS 5.0 when you use the WriteClient API to send data

RichH,

Thank you, I have read the bug report, I have also read the statements from IBI and New Atlanta.

I would like to know if anyone has actually measured the performance problem.

Cheers.

Francis,

We did implement what IBI has suggested to improve the performance but did not see any significant performance gains. However we are using WebFOCUS 5.2.5, at this level the servlet provided by IBI has performance issues which were later fixed from 5.3 level. Because of this I could measure the performance gains.

We had this problem back in May of last year while on 5.3.3 I think -- ultimately it was fixed in July by some setting changes.

I don't have any "hard" performance numbers anymore, but we logged a case and in it we noted delays of 15-60 seconds for initial loading of our BID. It would often be the first person that logged in in the morning that would notice the delay.

For what it's worth, we worked with techsupport to resolve this issue before the tech release ever became public -- but in the end, we changed the "Recycle worker processes" setting in IIS. The explanation was that IIS was shutting down idle processes (which included the ServletExec) after a short period of time (20 minutes or so). And then when a request was made, that process needed to start up again and that start-up was the delay that we were seeing.

I don't know if that answers your question or not, but the short answer is "yes" we saw significant performance increases in initial loading of the BID once this issue was resolved. Nowadays we're on Apache Tomcat, so I think the setting is moot.

Trav,

Thanks! Your comments do help. On our test server (5.3.2) I've noticed some odd behaviour that's not exactly like what you described: when I log in to a view with four quadrants that run fexes, only one of them take a long time to load, the others are fairly instantaneous. If I click the quadrant refresh icon, the result returns right away.

I have noticed other weird Java error messages and when I refresh the quadrant, they refresh correctly.

I will have to get IT to fix IIS and/or New Atlanta Servlet Exec.

Thank you very much.
