Report on Solaris Zope performance available
As Paul Browning has mentioned this already, I thought I'd chip in. A report on the performance of Zope under Solaris is available at <http://www.zope.org/Members/glpb/solaris> It's written mainly by Matt and Paul - I just helped out with test boxes and proof-reading, so those guys should really get the credit. There's a lot on threading in this report, as well as some thoughts as to how to get around the problems with Solaris, threads, Zope and Python. I'd like to draw your attention to this paragraph in particular; """ The University of Bristol was first exposed to the problem in April 2001. A year on the issue is now threatening the viability of growing number Zope-hosted applications at the institution. Moreover, the problem does nothing by way of reassuring decision-makers that Python offers a serious and practical alternative to the oncoming Java Juggernaut. """ Thoughts? Opinions? Ways forward?

Hi there... We, HeadNet, are having an frustrating problem... Our server (linux, apache, zope 2.5) is working fine, except when we are entering the site.... (http://www.headnet.dk) sometimes it reacts really quickly, and sometimes it is slow (up to 20-30 seconds!) One thing "helps": If we have the main-server restartet (there is approxiamtely 15-20 InstanceHomes, some of them have the same problem but not all...) it helps a bit... One of the strange things is that the speed of entering the site is going up and down... we actually have no idea, why or what to do about it... Have you had / are you having the same problem... we would very much like to hear from you... / Stoons : HeadNet :
Thanks everyone involved for a really interesting read. It wasn't clear to me whether you folks had 'solved' the problem or not, though. It sounded to me like you had. Did I read the report too quickly, and miss something? seb On Thu, 2002-03-21 at 07:41, Tony McDonald wrote:

I think "ameliorated" rather than "solved". There remain question marks over Solaris performance (and database adapters - though I'm not sure if this is Solaris specific). The further recommendations include: * Audit the state of Solaris system patches on the various machines used in the study and, if warranted, apply the latest patches that may impact on threading performance. Re-run the tests to assess whether performance has been effected. * Experiment with building Python using Sun's C compiler. * Explore the performance of adapters for other databases. We were rather hoping that the Solaris-using subset of the Zope community might get stuck into the last two.
