Daniel, I had a default '10 items per page' setup, anyhow, after a couple of dependency issues I've managed to rpm erase/install rrdtoll 1.4/1.2x, and, excluded rrdtool* and perl-rrdtool* from yum, (I'd have preferred to do like I managed on the other system, ver 1.2 on /usr/local/.., and, keep current version, but, well...) and, big performance uplift, web page generates/loads like in 5 seconds, if not less (versus almost 30 seconds) it's something to do with fonts caching that RRDTool does since 1.3 ? //from cacti ml: ... This indeed explains bad graphing times. RRDTool will (as I've deduced from a mailing to rrdtoll-users, so it's not my own knowledge) scan the font dir(s) on a first call. It will/shall cache the data and be faster on subsequent calls. But if there is no subsequent call as suggested by Larry, we will always face this time lag for rrdtool 1.3.x and up. ... // thanks again for all the suggestions -- Voytek -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
