I wonder why Zope is default set for handling 4 threads and 7 database connections.
Because these values are in general not too bad.
I tried inreasing threads to 20 and database connections to 30 by updating z2.py and DB.py, presuming that this will help to improve performance under heavy load.
Can anyone suggest what impact will be there if i do this , in Zope 2.6.1
You may drastically increase the RAM requirements of your Zope process: Each connection maintains its own (independent) ZODB cache. Main memory requirements therefore increases linearly with the number of connections.
