Not really. My "make world" time came down from 9h50 to 4h50 (approx) when I changed the DX-33 into a DX4-100. I got a lower time (around 4 hours) by putting /usr/obj elsewhere (and as I got 2 SCSI controllers, I put the disk there). /usr/src, /usr/obj and the CVS tree are all "async", it helps a lot. It also helps for CTM extraction/patch because the packets are extracted from sd11 (holds FTP) into sd12 (holds CVS) and then "cvs update" is on sd0 (holds /usr/src).
