After some more tests i made,i found out that having an 68000/14.2Mhz along with the gotek drive, actually reduces loading times ~20%-25% in many games!
As you might already figure, this is because many games have data on disk COMPRESSED, so after loading them from disk, they need to be uncompressed!
And since compression/decompression procedures are rather cpu intensive, having the cpu in double clock speed, reduces fair enough the actual waiting times!
For example in agony, using disks or gotek with a standard amiga it needs about 125sec from pressing fire until starting to play. Using 68000/14 and gotek this time reduces to ~100sec!
