Hello Iperf Community, The Network Technologies Lab at Intel has been making great use of iperf in our testing. We've made some changes to suit our needs:
1) Replaced the gettimeofday() call with 'rdtsc' instruction to avoid a kernel transition in the fast path. 2) IO threads no longer block on the reporter thread. This change improved and stabilized performance, particularly for small IOs. 3) Added a sendfile option that uses the sendfile() system call. Some OSs (Linux) implement sendfile as a zero copy transmit. Is anyone actively maintaining iperf anymore? We're interested to work with a maintainer to get these changes into the main version. I expect some independent validation will be necessary. Thanks for any feedback, -steve ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
