peformance of Allegro 4.0 Beta CLOS on Sparc
I tried running the 4.0 Beta release of Allegro on a Sparc
over the weekend. I wanted to compare the performance of
the new native CLOS with that of PCL in Allegro on my PMAX.
The new CLOS on the Sparc did make-instance on simple classes
10 times faster than PCL on the PMAX. Class definitions were
"much" faster also, I'd guess 3-5 times faster, though I didn't
time it. The whole Oz system, which is heavily CLOS based,
seemed to run about twice as fast on the SPARC, though again
I didn't time it.
I had wanted to get a general sense of the speedups that might
be in store with the new CLOS, and all in all I was very impressed.
I am greatly looking forward to running the new Allegro on my
collection of PMAXen, when that system is available for beta use.
[By the way: If this new system comes with a profiler, that would
be a great help, too. If it is very expensive, perhaps we could
get it for one or two machines of each type of architecture and
