However, i *actually* noticed the 'slow' speed of my A3000 with KS3.1 ROMS - as reported by Sysinfo.

When i first got my towerised A3000 five yrs ago - all the way from Germany - it came with 2mb chip + 4mb fast, but due to my lack of experience, i inadvertently screwed up the zip rams Thereafter i cold-storaged my A3000 (i mean can you run any program productively with a 2mb amiga?)

Recently i bought a Fastlane pop'd with a whopping 64mb ram (the max is 256mb but you'd have to be extreme lucky &/or rich to get this kind of ram modules), and got all excited to revive my A3000.

Indeed the extra ram speed up the operations on the A3000 (plain WB3.1) tremendously. So i installed Sysinfo for the 1st time on this system to check. The report was a shock... so very perplexing! altho in reality i'm very happy with the RAM boost.

Perhaps there's some flaw with the Sysinfo?


Why would you think this is due to the kickstart?  It's actually due to the different speed of access to your RAM.

For fastest to slowest access time...
FastRAM on accelerator card
FastRAM on motherboard
FastRAM on ZorroIII
FastRAM on ZorroII
RangerMem (A500 bay)
CHIP RAM

The fast RAM that was on your motherboard would be faster access than the fast RAM on your ZIII board, hence the overall performance loss of not having RAM on the motherboard.  

I've never heard of a ROM having a slower access time than the 1.4 SuperKickstart.  In fact, either way, your ROM timing is going to be exactly what you set your motherboard ROM timing jumpers to.   :lol:

If you really want to boost performance on ROM calls, like others have said, get an accelerator and blizkick your ROM to the FastRAM on your accelerator.  That'll give you a speed boost.
