Linux OS latencies

Purpose:

The purpose of this test is to measure various Linux latencies

Additional Information

latconnect localhost - measures TCP/IP connection latency

lat_proc fork - latency to fork an identical process and have one exit.

lat_proc exec - latency to fork an identical process and run a program.

lat_proc procedure - latency to fork an identical process and ask the system shell to find a program and run it

lat_select tcp - latency to select 200 tcp file descriptors

lat_sem - semaphore latency

lat_sig install - latency to install a signal

lat_sig catch - latency to catch a signal

lat_tcp localhost - latency for a TCP server to localhost

lat_unix - interprocess socket communication latency
