You say it's slow? No! it's terribly, awfully SLOOOW! On my aga/060 it takes 0.3-0.4 secs just to renew screen, and all the process is visible - even no doublebuffer!
This piece of software is totally amiga-unfriendly and even does not utilize neither any 'industry-standard' (meaning amiga standard) c2p, nor other amiga-native tricks.
I anticipate quite a normal speed on those 'modern' pegasoses/etc, but what does it mean? Just a peecee-like style of coding: we have a lot of resources, so we can do everything not ever taking care of doing things better and faster...
