Here's what I think I know (though I could be wrong): - The pool size is the number of ZODB connections maintained. - It should be at least as high as the number of zserver threads + 1 I think? - I use zserver threads 6 and pool_size 10, works fine. - zserver threads is basically a measure of how many concurrent requests you want your server to be able to handle, by default, it's 4 (and pool size 7 IIRC?). - The downside is you have to balance this with the cache size, since the cache size is per thread ... So your RAM usage could go up significantly.
