Hi guys, Have been thru all optimisations process (caching etc .....) but my zope still runs like a dog. I am fairly confident about my zope set up and start to think the pb is the box itself(i did anaother install on older box with same apache+proxy config and zope proudly flies !!) my config is : Dell poweredge 1750 + redhat SMP 2.4.20 stock kernel. I ve got this in dmesg : "" application bug: python2.3(10123) has SIGCHLD set to SIG_IGN but calls wait(). (see the NOTES section of 'man 2 wait'). Workaround activated """ Dunno if this could be the issue . I try to run another Python (from rpm) but got the same messages) Any one noticing same pb on dell/linux with RH9 boxes ? Anyone could point me out to checks i may have not done yet ? Thanx a lot Seb
