Subject: One Designer's Sun Solaris 7.0 To Red Hat 6.2 Linux PC Benchmark
Hi, John,
To add to your latest SNUG information on Sun's vs Linux, for me, the issue
came up when I asked the SGI and HP people at the recent SNUG'01 conference
about such data. They said I could see a significant speed-up based on the
speed of the processor. Since then I've done a couple of small comparisons
to get an idea if they really knew what they were talking about.
The systems I used were a Sun Enterprise 420 (4x450MHz processor) running
Solaris 7 and a VA Linux Systems 2200 Series 2U Linux Server (2x800MHz
Pentium III) running Red Hat Linux 6.2. A direct MHz speed comparison has
the PC running 1.8x Mhz of the Sun.
The following table lists the values reported back from the Unix "time"
command on a couple of small synthesis jobs.
job cpu Sun cpu PC ratio
1 3059 sec 1715 sec 1.8x
2 652 347 1.9x
Seems to track the MHz scale fairly nicely. I haven't tried anything that
would push the memory limitations, etc., but at least for reasonably sized
blocks of logic, seems like this is a no-brainer.
