I'm interested in the values that you have set for the store-janitor in cocoon.xconf based on your JVM settings below, as well as any max-pool changes. My setup is somewhat similar: Applications ------------------------ Cocoon 2.1.6 Apache Tomcat 5.0.28 JVM 1.4.2_07 Hardware/Software ------------------------ Dual Xeon 3.06 GHz 3 GB RAM RedHat Enterprise AS 3 I went ahead and used the JVM settings you provided, yet I was always faced with about a 2-second lag for each page request, no matter how many times I visited the page. I hadn't even scaled the numbers you provided for min and max heap size, etc. The only thing I changed in the store-janitor was the freememory and heapsize parameters to the following: freememory = 81472000 (about 15% of the heapsize) heapsize = 536000000 (slightly less than 512 MB) I didn't change any pool sizes. Are you getting about a 2-second lag for each page request as well? This memory allocation has always been a mystery for me... Jon
