OK.. I don't have my netlists on my day machine here... I'll put
together a test case this evening.<br>
Thanks much...<br>

<pre wrap="">Hi-
I recently built an Athlon 64 X2 3800+ box for running ngspice
simulations on. Performance is poor, however. I have ngspice running
on a MacBook with a 1.83GHz Intel Core Duo and it's about 5-6x faster
than the Athlon 64 with a 2.0GHz clock! Any suggestions on how I can
benchmark ngspice performance more quantitatively? Or compile options I
need to watch for? On the Athlon64, I've tried both a pre-built RPM,
and recompiling ngspice with the lib64 libraries with no difference in
result. Still dog slow on the Athlon. I've been running transient
analyses on fairly small netlists (<1000 devices). Note that I get the
same answers from both the x64 and i386 versions, just at vastly
different times.
Thanks for any suggestions...
