Re^4: OT How fast a cpu to overwhelm Time::HiRes

I don't think so, I can see the same results with his code, and if I run it through strace I get

gettimeofday({1133398137, 976963}, NULL) = 0
read(3, "", 4096)                       = 0
close(3)                                = 0
gettimeofday({1133398137, 977352}, NULL) = 0
gettimeofday({1133398137, 977383}, NULL) = 0
gettimeofday({1133398137, 977417}, NULL) = 0
gettimeofday({1133398137, 977441}, NULL) = 0
write(1, "1133398137977417\n113339813797744"..., 341133398137977417
1133398137977441) = 34

So you can see that all the gettimeofday system calls are actually taking place and the values are being printed out. It's possible of course that this is an artifact of the tracing, and the value is cached otherwise, but that doesn't seem too likely.

Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. -- Brian W. Kernighan
