Hi all, Just FYI, we have switch mod_perl2 off on all validator servers again. Running under mod-perl seemed like a good idea, but there were some issues we're having trouble explaining, like how the load remained really, really high on the machines (apache2 processes using up a lot of CPU) even when very few requests were being received. Switcing off mod_perl means more resource forks, and a slightly slower validation process, but ultimately, less load and less wait, it seems. Go figure. I still want to try some of the performance tweaks you suggested, Ville [1] (avoiding copying content, undef-ing after use, etc). Gerald also was suggesting looking at e.g BSD::Resource or any ulimit- like system, to avoid having some "check" processes spin away and hog CPU. Worth a shot.
