To give you a little data .... I have the following machines:
P: 266 mhz pentium, isa ne2000 clone
N: 486/66, 2 ne2000 clones, scsi disks
S: 486/66, ne2000 clone, ide disk
D: 200 mhz pentium pro, isa ne2000 and intel 100 mb ether, scsi disk
W: 200 mhz pentium pro, intel 100 mhz ether, ide disk
All run NetBSD, N & S are at 1.2, others at 1.3.
Config:
---10 Mb ether -------N-------P---------D---------
| |
| |
10 Mb 100 Mb
| |

S W
So N and D are the gateways.
Timings taken are as follows (from ftp)
P -> N, 6 Mb file, 560 KB/sec
P -> N -> S, 6 Mb file, 474 KB/sec
P -> D, 6 Mb file, 862 KB/sec
P -> D -> W, 6 mb file, 787 KB/sec
D -> W, 6 Mb file, 2.42 MB/sec
This is far from a conclusive study, but I have found that N has worked just fine
as a gateway for the last 3 years as well as a nice WWW server!
The newer machines are indeed faster and should give you better performance.
But the older ones do work. Notice, network speed can also change your
performance!
