Maybe some of you are interrested...
11.0 allows to configure the amount of memory (RAM) used as PageCache.
Default is 2500 MB, we increased this value in our main.config to 8000 on
March 26th.
<PageBuilder>
<!-- The threshold in MB of used ServerService memory that triggers a
PagebuilderCache clean up operation. -->
<PageCacheMemoryThreshold>8000</PageCacheMemoryThreshold>
</PageBuilder>
When we look to PageCache.log we see frequent cache-cleanup-operations
until March 26th. With 8GB of in memory PageCache WSM is now able to hold
the complete PageCache within memory. (Our WSM has 16GB of RAM.) So we
removed one prior existing bottleneck and improved performance.
Depending on your environment and your projects it may be worth to have a
look at your PageCache.log
