Hello Java Web-AS gurus,
we use for our portal a content management system, which generates JSPs. While using SPS13 of the EP 7.0 we noticed, that the compiling of the JSPs take very much time (around 5-8 seconds per JSP first time).
We search in the marketplace and find the note [1020365|https://service.sap.com/sap/support/notes/1020365], where is described, that SPS13 has performance problems by compiling JSPs. The issue should be fixed with SPS14. We update now our Quality system to SPS 15 and the JSPs only need 1-2 seconds to compile like before in older versions.
But now we patch also our productive system, but here the effect was less. Each JSP takes over 5 seconds to compile. While compiling, the javac process takes 100% of the CPU.
Our Quality is a central system installation on VM ware with 4GB RAM and MS SQL 2000 server on the same server. But our productive servers are in a distributed landscape, which 6 GB RAM on every Dialog Instance and a seperate MS SQL DB cluster. It has really much more power than the Quality system.
I can't understand, why even simple JSPs (3-6 lines) always take 5 seconds to compile. It seems, that the time is set somewhere.
Can somebody help us or have anybody a idea, what we can try?
Best Regards
Frank
