It would be faster to do open+fstat rather than stat+open (as

but that might be too radical a change. Anybody have

sometimes folks are lazy and ask for zeroed memory out of habit, when they

I'm currently studying profiling data from an httpd built from
a CVS snapshot earlier today.
In general, the performance of 2.0 is starting to look good.
Here are the top 30 functions, ranked according to their CPU utilization.
