After much testing, I have managed to overcome the limits on file descriptors and such
on linux; and have a mysql daemon that is fairly lean and able to support several
thousand simultaneous connections.
I still, though, would like to see what kind of improvment gcc-3.0.4 makes as opposed
to 2.95.
This build error that I had before (it misdetected the gethostbyname_r function) still
plagues me, and I have been unable to find a work around for it. Can anyone lend
assistance? Attached below (they've also come through the list before on this thread)
are the relevant lines from my config.log with regards to the gethost* function(s)
Thanks
