This is my experience (not war here): I have 20mb of RAM and when running
under Windows 95 DJGPP uses a lot the harddisk... much slower... I
recommend using DJGPP under Windows 95 if you have more than 32mb of RAM.
Using Norton Cache (NCACHE2) with a cache of 8mb does a great job! DJGPP
donīt uses the harddisk! BTW, my drive is compressed, so, DJGPP uses less
physical harddisk, so the cache is more efficient.
You have to try your self wich is the best configuration that works for
you, try under Windows 95, under DOS with caches and different sizes of
it... and try with ramdrives also.
BTW: RHIDE donīt works under Linux DOSEMU 0.66... someone knows how to get
it working if it is possible?
Just my opinion... Goodbye!
