Hi !
since some weeks, i've got a really poor performance, when i want to see graphs on the test-page or in trend-page ..
I'm running xymon-4.3.7 ...
It's still need 4-8 seconds or more to generate these graphs and the top-output shows till 6 showgraph.cgi-processes with a huge CPU-usage
top - 14:01:20 up 143 days, 22:53, 7 users, load average: 2.05, 1.34, 0.69 Tasks: 320 total, 7 running, 312 sleeping, 1 stopped, 0 zombie Cpu(s): 1.6%us, 0.7%sy, 0.1%ni, 96.9%id, 0.7%wa, 0.0%hi, 0.1%si, 0.0%st Mem: 24942104k total, 6083748k used, 18858356k free, 431604k buffers Swap: 0k total, 0k used, 0k free, 3084868k cached

Has somebody an idea what's hanging in the system or how i could analyse this poor performence-problem ?
Cheers,
Martin
