First benchmark results
Executive summary:
HP-UX is shown out-of-the-box, with no parameter adjustments which could help it show better in these benchmarks.
HP-UX, a mature much-tuned kernel and Linux, a not fully functional and never tuned on HP hardware kernel, are competitive in a great many areas. HP-UX is faster in some areas, and Linux is faster than HP-UX in fewer areas. This portends a bright future for Linux on parisc!
HPUX, is MUCH faster than Linux at fork/exec and pipe and unix/tcp socket bandwidths. Note: Linux fork/exec got a
lot faster with the recent cache-flushing changes. Linux wins big on stat, open/close, file create/delete (sometimes > 100:1).
Linux beats HPUX in the 2-process context-switch trials, but not in the 8 or 16-process trials.
The 100MHz gecko is roughly 8x slower than the 400MHz C3000 on compute-bound benchmarks, re-emphasizing that MHz is not an entirely trustworthy performance predictor.
Caveats:
HPUX was not optimized for this benchmark. Changing the fs_async flag might make a huge improvement in the file-system-related performance.
The "TCP conn" data should not be trusted at all.
LOTS OF DATA IS OBSCURED and possibly MISREPRESENTED by this summary. The hoards of data upon which this summary is based is available at http://puffin.external.hp.com/~bame/lmbench-2beta1/results.
c3k-hpux is an active in-use HPUX box with variable loads runing all the standard daemons therefore some benchmark results are slow.
Lmbench 2beta1 by its name is clearly "beta" software (though it seems to work fine). More info about lmbench: http://www.bitmover.com/lmbench
Some test programs on Linux still require manual intervention.
