History

#1 Updated by John Abbott about 10 years ago

Bruns mentioned sometime ago (1 year?) that CoCoALib-0.9951 was about 20% faster than a later version.

20140127: Christof is running some tests on his linux box, and he is observing quite significant variation in relative execution speeds (comparing 0.9951, 0.99531 CVS, 0.99531 JAA "private" version).

20140128: The speed comparison did not show evidence of 0.9951 being uniformly faster than the current version (0.99531); nevertheless, there were considerable variations in relative performance.

We are now regarding the reported apparent drop in performance as an occasional phenomenon (perhaps due to memory access patterns and mysterious cache effects?)
