Let us see some facts. From BYTE magazines:

		IIcx	IIci	ALR/25	SIA/32

Matrix		16.2	10.5	 2.62	 2.10
Sieve		31.4	19.8	14.06	11.02
Sort		29.7	19.4	10.52	 8.26


Mac IIcx, 16Mhz, 120ns Dram, No cach, No Burst fill mode.
Mac IIci, 25Mhz, 80ns  Dram, No cash, Burst fill mode.

ALR 386/25, 25Mhz, 80ns Dram, Cash, interleaved memory.
SIA 386/32, 32Mhz, 80ns Dram, Cash, interleaved memory.

Since the IIci is only 35% faster than the IIcx, I could not expect
the TT to be more than 20% faster that the IIcx.
