Hi,
Can you suggest anything to increase the performance of CPS? I
found something about the RAM Cache, but could not implement it. So
I would appeciate any help...
First, you have to know what is the bottleneck. This can heavily
depend on your usage pattern. The tool I use for this is ZopeProfiler
(google that). You need to python knowledge and a good grasp of CPS
architecture.
Now there are many different RAM Cache within Zope/CPS:
- Portlets cache (tuning of cache parameters can be tricky, the
default values are quite ok). You really need to understand the model
for this.
- CPSSkins cache
- Zope's RAMCacheManager based caches: RAM Cache for directories,
you can put some scripts in cache too.
- ZODB object caching (especially important in ZEO configurations)
It gets worth switching to CPSLuceneCatalog/NXLucene from about 10^5
documents, but this requires some serious expertise.
