Looking for information about "linux-gate.so.1" I have found this webpage: http://www.trilithium.com/johan/2005/08/linux-gate/
I think this could be the reason for the slowdown in my case because symptoms match. My program is invoking 10 million system calls for the first random test and it happens only in the dynamic version. My CPU is an Intel Pentium IV.
Ahaha, so if I understand you the strace output is huge for the dynamic one and smaller for the static one?
Can you post an example of one of the "10 million" syscalls that is present in the strace output for the dynamic case (if I understood you correctly)?
My glibc version is 2.4-8: # rpm -qa | grep glibc glibc-kernheaders-3.0-5.2 glibc-common-2.4-8 glibc-headers-2.4-8 glibc-2.4-8 glibc-devel-2.4-8 Do you think this could be the cause. How to fix it? Thanks!
There are some magic things down /proc/sys/kernel/ that you might want to meddle with to see if they affect the situation. Eg echo "0" >/proc/sys/kernel/randomize_va_space echo "0" >/proc/sys/kernel/exec-shieldAnother idea, perhaps to to give a static libm and keep the dynamic libc stuff eg
gcc blah.c /usr/lib/libm.anot sure if that will work but worth a try. Then the ldd for the resulting binary should no longer reference libm.
