> Are IFL engines slowed down compared to a GP engine?

Phil:

Amazing the amount of incorrect info on the list on this subject.

IFLs run at "rated speed" of the processor. That is to say, they run as
fast as the standard (or "general purpose") processor on the system can
run. Basically find the speed of the fastest uni-processor on the
system, and the IFL (and ICF) will run at that speed. Now this speed can
vary between systems quite a bit.

On the z800 assume the 001 runs around 190 MIPs and so will the IFLs
even if you have a sub-uni (like the 0A1).

On the MP3000 models the uni runs at 115 MIPs.
On the z900-10x models the uni runs at 235 MIPs.
On the z900-1Cx/11x models the uni runs at 240 MIPs.
On the z900-2Cx/21x models the uni runs at 290 MIPs.

All MIPs ratings are of course meaningless.

Of course you will be subject to MP effect (shared cache, etc.) so your
mileage will vary.
