There's a good description of what the accept mutex is used for on the Apache Performance Notes page at http://httpd.apache.org/docs/misc/perf-tuning.html (search down for "accept Serialization"). Essentially, the call to accept() needs to be serialized to support servers that listen on multiple ports. Also, serialization is a performance optimization on servers that only listen on one port. I assume that apaci and/or configure made a good guess for your system when you compiled Apache, but you can experiment with other methods. Using a different mutex, if it works at all, should only help or hurt performance (perhaps using fcntl is really fast compared to pthreads on your OS). -- Kyle Oppenheim Tellme Networks, Inc. http://www.tellme.com
