This seems to randomly occur with any files about 10k or larger. For instance, I have been using a test file of 140K, and it can take 0.5 or 4.8 seconds to transfer. When using the sparc platform, it always only takes 0.5 seconds. I noticed this as we are using an external monitoring system (Gomez.com) and we started seeing these wildly varying times for transaction processing. I have tried a cut down SSL setup for testing, and examined every directive and option, and I can't make sense of the problem. I'm using the following configuration string, and I'd be happy to include the configuration setups.. I can move the bare-bones configuration between the sparc and x86 platforms and get normal response on the sparc, and irregular on the x86.random device can make a huge difference. What do you use for random data? /dev/random or /dev/urandom? If the rofmer, try the latter if it helps.
Good point. But to have some prove at hand, don't change the random device yet - instead monitor /proc/sys/kernel/random/entropy_avail with e.g. watch. If your're going of of random bytes - ka-ching :) Regards, Edgar --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
