Thanks Enrico and Daniel, you're right. glibc was caching getpid(); but this is not the root cause of this behavior. Going further, I decide to use call getpid without glibc, using syscall(SYS_getpid) to test this behavior and it happened again. Calling it once, the test consumes about 7k CPU cycles and 10 calls consumes about 10k CPU cycles. Any ideas ?
Can you post a pointer to your code and information about how you got this numbers? thanks, Daniel.
