We have a PC application that requires a high performance PC shell
for under $5K.  Recently, we made a decision against PC-KAPPA due to
problems we were having with performance (even though it meets our
needs w.r.t. functionality).  Basically, we are looking at a minimum
performance expectation of around 100 - 200 rules per second based on
crude estimates of the application.

We are considering CLIPS but have inconsistent data ranging from 50
rps to 600 rps.  Does anyone have performance data on a 486/25 based
machine?  We are also concerned with CLIPS' rule language (i.e. not
easy for a non-programmer to modify/maintain).

Any feedback on other shells out there would be greatly appreciated.
I imagine this is not a new question, so I would appreciate getting a
synopsis of previous discussions.

Thanks in advance.
