Full Discussion: Efficient logging of time measurements
Top Forums Programming Efficient logging of time measurements Post 302767161 by tamil.pamaran on Wednesday 6th of February 2013 10:12:44 AM

Thanks Venam,

I feel creating a new thread for each thread in focus, would be a bad idea. I am thinking of using time() system call to measure time differences. There should not be any race conditions among the threads, in calling time().

However, once measurement is taken, there is a race condition when multiple threads trying to log. Using semaphore will in turn will create bottleneck.

I am not familiar with syslog(). Can that be useful here?
