Thanks for testing KnightX Graham
At this time, the new 2.8 version has not made significant progress against other programs
I think that the program has reached its limits, because of bugs or bad parameter values somewhere
Or bad implementation, or lack of time to evaluate precisely a modification... Several possible causes
It was written in 1995 in C language and was (badly) designed to be fast. At that time I didn't imagine that 24 years later I would rediscover it and modify it, with not the same ability to concentrate
Anyway, either I make a significant progress, either I rewrite it entirely in C++
it may take some time before a new version comes out
