I think Florent had the Zope default in mind (which is 5.000 rather than 4.000 when I am right -- but this does not really matter). -- Dieter ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

It's unclear to me which default we're talking about. ZODB's DB.__init__ has cache_size=400 (not 4000) as the default. The example ZEO client in skel/etc/zope.conf.in sets # cache-size 5000 as its "default". Since this isn't a "one size fits all" setting anyway, I doubt that changing the default would help more than it would hurt. ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

That may already be a bit large: We use 15.000 with 6 workers and our Zope easily comsumes about 1 to 1.5 GB of RAM. I would keep the 4.000 default in order not to bring newbies with low RAM into problems. Experts can easily reconfigue the cache size. -- Dieter ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
[Zope-dev] Default ZODB cache size
How about boosting the default ZODB cache_size to something less ridiculous than the default 4000 ? I propose changing etc/zope.conf.skel to have an explicit value of 2.
