Re: [squid-users] squid cpu problem

Dear Eliezer
as to my tests on 3.1 it can handle about 100Mbps with single core with
about of 40% cpu load on intel xeon or AMD X6 without the CPU spikes

i have 4 servers 3 on old gentoo kernel and one on newer ( portage,
kernel and libtool ) the only new one has the spikes
i had to add the GCC flags on the new one due to an error in compile

g++: warning: switch '-fhuge-objects' is no longer supported
tools.cc: In function 'void no_suid()':
tools.cc:778:14: error: ignoring return value of 'int setuid(__uid_t)',
declared with attribute warn_unused_result [-Werror=unused-result]
tools.cc: In function 'void enter_suid()':
tools.cc:756:14: error: ignoring return value of 'int setuid(__uid_t)',
declared with attribute warn_unused_result [-Werror=unused-result]
cc1plus: all warnings being treated as errors
make[3]: *** [tools.o] Error 1

make[1]: *** [all] Error 2

make: *** [all-recursive] Error 1

adding cflags solved the problem ...
so the new one is the only one with the cflags
is there any effect for the cflags on performance and gcc errors (
while loops ) which causes the CPU to spike to 100% ????

best regards
