Subject: time:ing non-cygwin apps
Date: Wed, 05 Sep 2001 03:57:00 -0000 [thread overview]
Message-ID: <u67lmjtlxeo.fsf@rachel.vtab.com> (raw)
Hi,
I'm trying to get some useful information about the execution time of
non-cygwin app. To illustrate, run the following shell-script:
--[ cygwintime.sh ]--
#!/bin/bash
cat > foo.c <<EOF
int main() {
int i;
for (i=0; i < 1000000000; i++);
}
EOF
gcc foo.c -o foo-cygwin
gcc -mno-cygwin foo.c -o foo-native
time ./foo-cygwin
time ./foo-native
--[ ... ]--
On my machine, I get the following output:
[0][SEBASTIAN] ~ -> ./cygwintime.sh
real 0m4.426s
user 0m4.346s
sys 0m0.010s
real 0m4.006s
user 0m0.010s
sys 0m0.010s
[0][SEBASTIAN] ~ ->
Note that the -mno-cygwin application takes almost no user or sys
time, but several seconds real time, as if the time command is unable
to report the time of non-cygwin applications.
Naturally, I'd like to get similar results in both cases. Is there any
way I can get round this? (Is it a bug or a feature? ;-))
