It seems that Bruce Evans said:

Results for my EISA BT-747S and AHA-1740 controllers for perspective:
486DX-33 EISA/VLB, 32 MB
[[ BT-747S + Conner CFP-1080S fast disk ]]
Command overhead is 2157 usec (time_4096 = 2598, time_8192 = 3039)
transfer speed is 9.29262e+06 bytes/sec
[[ AHA-1740 + Seagate Hawk ST-31200N fast disk ]]
Command overhead is 2332 usec (time_4096 = 2806, time_8192 = 3280)
transfer speed is 8.6371e+06 bytes/sec
BTW, my last "make world" gave this:

Without running X11. Not too bad for an "old" 486DX-33 :-)
