Some mmu questions

I have a 4000 68040/25mhz, 18Meg Fast.

I see mmu.lha and mmulib.lha ~aminet and, since they seem to change the os with a lot of patches, im asking b4 trying:

-If its going to speed up demos/ games, do i need mmu.lha or just only mmulib.lha? (i wouldnt really use mmu for any other thing but speed.)
-do i get more speed running demos, but maintaining compatibility?
-do i loose lots of ram (more than 128kb)?
-will the patches creates backup from the old files?
-i use a lot of patches to speed up the system - any problem?

Tks a lot

There will be no performance increase, but the idea is to have more compatable way of using the mmu. more programs can use the mmu at once and offeres a way for new programs to easily access the mmu for useful stuff and even offer managed virtual mem (but i dont think this ever appeared). Only app i can think off that made use of the mmu.lib is ASP spectrum emu.

do you really call loosing 128k lots of mem ?

incidently lots of so called speed up patches usualy end up slowing things down as you have alot moe running in the background(and take up precious k's ) so should really sniff out the ones that really do benefit the system rarther then theoreticle speedups.

Another program who benefit of the mmu is 68k linux. In fact it can't work on Amigas without mmu.
