Re: [squid-users] % of improvement in async I/O

I have tried to compile my Squid 2.4s1 on RH 6.2 with async-io enabled
keeping everything default (e.g. libc, gcc etc) but after not more than five
minutes i got 'Recieved Segmentation Fault dying' in my cache.log and Squid
got crashed. I don't think that the 'libc' that comes with RH 6.2 can
perform better.
