- I've used the Jolitz's 386 port on a 386DX/25. I switched to BSDI's 386
- port as I wanted to get my software developed, not work on the OS. However,
- for this discussion, they should be performing about the same when run on
- the same hardware.
-
- In short: it screams! I'm very happy with the speed of ISA systems running
- Unix. I'm running an Everex 386DX/25, 16Mb, 64Kb cache, motherboard SVGA,
- using both the built-in IDE and an Adaptec 1542B with a Maxtor 8760S I had
- laying around. I've also used it with all of /usr NFS mounted from a Sun 3/60
- and my login directory NFS mounted from a VAX 785. Disk I/O-intensive oper-
- ations are faster on the 386 using NFS served disks than locally on the VAX,
- which is amazing considering that the VAX is serving them to the 386.
-
- Also, things that take an hour to compile on the VAX take only 10 minutes
- on the 386. I'm now doing most of my Unix development on the 386.
