[armedbear-devel] Maxima status: performance measurement

[Erik Huelsmann]

Hi Robert, hi all,


Today, I ran Maxima through ABCL's profiler to see what's our current
status. With our combined changes, we seem to have reduced the
throughput time of the Maxima tests on my system from 2200 secs to
roughly 1800 secs between October and now.

These are the hotest spots now:

As you can see, the DGR(F) functions which relate to the integrator
tests have now been removed from being the main bottle necks. It looks
like some evaluator is now our 'hottest' spot. Robert, could you help
us to see what we should do to optimize the functions which are now
our main performance issue?


Thanks in advance!

Bye,

Erik.
