Hi all,
My zope clients (Zope2-2.12.11) allways start with 5 theads although
zserver-threads is 2 in my zope.conf file.
I am using ps -eLf for theads counter.
If for zserver-threads I use the values 1, 2 or 3 I get 5 theads.
A higher value give me 2 threads more. I mean, for 4 I get 6, for 15,

That's something proposed several times in the list.
In our installation, we used the default (4 threads) for a long
time -- until we met overload situations (all 4 threads in
I just spent a few minutes googling it and failed, but I thought I read on
the Zope wiki that for higher trafic sites, it was better to have bigger
caches (50,000+) and fewer threads (2).

The term high traffic site doesn't mean a thing when it comes

Well, I have been using Zope for over 6 years and I still don't think I
have mastered what is truly best other than get a good server, with a lot
of RAM and bump up your threads * cache to use up about 50% of it.

Am I gleaming from that that you are proposing a less-is-more approach to
threads?
Here is what I have been using:
- Zope 2.7.8 (Plone 2.1.2)
- RH Linux
- AMD Athlon 64 3200+ 2.0 GHz
- 2GB DDR RAM
- 120,000 hits a day
- 392,036 objects in database
- 2 threads
- 100,000 object cache size

You do not need to worry about it unless you have a really unusual
setup. The default is fine for 99.9% of all situations.

There is no typical value. Changing the thread number and pool size

Where do you see the gain? More threads and connection also means
more caches that need to be updated/invalidated

The default values for thread number and connection pool covers all

Ok, much clearer now...
I might focus on cache sizes then.

It depends on how intensively you are using additional (application level)
threads:
Each thread using persistent objects requires in general
