I agree with Aditya, the surest test of performance between a GPOS and an RTOS is the worst-case jitter time., which btw, HAS TO be deterministic for any RTOS. I had worked on RTLinux a LONG TIME ago, on Rtlinux v2.0 and am not too well-versed with the changes, but doesn't the RTLinux (even the Free version) come with an example/ directory whcih has loads of performace tests, regressions, heavy loads, example with GNUPlot, etc ? Writing these same programs in Linux and using the simple "time" command, you can compare the performances. Raseel.
