0I just brought up the RELATUS Natural Language System (with a new knowledge
representation system) on the XL1200.  Running on an XL1220 in 8.0 with
floating point accelerator and 4 megawords of memory, RELATUS parsed and
represented the canonical 10 page text (250 sentences) in 1 minute (1.17
minutes without without-interrupts).  For the same text, the time in 7.2 on
3640 was somewhat more than 6 minutes.  This is a factor of 6 increase.

This timing is a very crude indicator of the performance increase for a large
system (30K blocks in the world load), especially since a new, unoptimized
knowledge representation is in place.  But, the RELATUS benchmark does run
lots of code, exercise most lisp features, and depend on paging performance.
I'll report again when I have the system running on 3640s.

Intuitively, the increased performance is striking for the kinds of activities
I have just done: file-io, compiling, world building, switching contexts.  I
estimate it increased my productivity by a factor of three.

I am looking forward to adding more functionality and slowing RELATUS back
down to human speeds.


Here's a trace of the timings.
