Hello,
Thanks for this, time is useful when checking the run time of actual programs, but I need to know how long my data is taking to Serialize, so that I can figure out if it is to slow, or if there are ways of speeding it up, because when I saved from the client, it lagged the server. In this case, I actually need some sort of mechenism that will give me time with MS precision so that I can check that.

Hi Ty,
Look at the time function. So time ls will give you some information about real, user and system times consumed by ls..

Subject: timing functions and chunks of code in *nix?



Hello all,
I know windows exposes high-resolution timers to do this sorta thing, but I'm curious how I could do the same in Linux? Is there something that will give me timing in ms? so: 
prev = gettime();
myfunc();
now = gettime();
printf("you spent %d ms.\n", prev-now);

Thanks,
