    FYI – I have been consistently having problems with my server crashing and load spiking up to 100 at worst. After in depth troubleshooting today, I found out that it was Olimometer which was somehow causing a ‘fork bomb’ via PHP. After disabling Olimometer, the problems went away. Something you really need to take a look into.

    The Olimometer can cause high CPU load on a heavily used site due to the graphic manipulation of the GD library upon which it is dependant. Since this plugin was written many years ago, web technologies have moved on significantly and I’m currently investigating a cleaner CSS/HTML way of implementing the thermometer images. I can’t give timescales, but I am looking into it.

    one (i think fairly simple) thing you might consider is generating a static image that can be cached until there are changes needed rather than regenerating the image on each request. on the site where i am using this plugin, we might actually change the olimometer once every few days, but it seems like every request makes the plugin do work.
