I haven't built my own Apache yet, but I am a programmer. The code should have some type of #ifdef which will be used to compile in SMP support. Applications are not SMP capable by default usually. Sometimes applications have runtime library switching, but I find that many Open Source projects go for lean and mean. Do a search for SMP over the whole source directory and see if you can locate the #define you need to create.

I have another Java based application running on the server, and the load is correctly distributed for that application. I also have few other instances of Apache running on multi-processor Sun system. On those systems, the CPU utilization is fairly distributed. Any reason why this might be happening on the x86? Could it be a issue with the gcc that came with 2.1? Or is my compilation of Apache @ Fault? Thanks.
