Hi. I'm about to purchase a 486DX2-66 PC to install FreeBSD 2.0 in it and use it
as a server for NFS, printers, etc.

Among its requirements, I have to use a fast SCSI-II controller, and a fast
Ethernet network adapter. I want to use either PCI or VESA cards for those two,
as I think that will be the fastest. Am I right? Would EISA be faster?

Regarding VLB SCSI controllers, I've used and tested the Adaptec 2842 with a
Conner CFP-1060S drive, and IOZone reports about 1.5-2 Mb/sec for writing and
2.5-3.3 Mb/sec for reading (I've excluded figures that are too high for reading
speed because of the Unix cache).

Regarding PCI SCSI controllers, I haven't tested any.

I'd appreciate that someone e-mail me the speed report generated by iozone with
different SCSI controllers, specially the PCI controllers supported by FreeBSD
(Buslogic 946c and NCR 53810). Is the Adaptec 2940 supported already, or support
isn't ready yet? By the way, what does the 2940 have, so that it is about 4-5
times more expensive than the NCR, for example?

With respect to Ethernet adapters, I have no experience with VESA or PCI ones.
The release notes list a lot of network adapters supported by FreeBSD, but they
don't say if they are ISA, EISA, PCI or VESA. Does that matter?

For instance, I've seen VESA network adapters that are compatible with NE-2000.
Does that mean that they can be used with FreeBSD just as if they were 16-bit ISA
cards, but much faster?

Again, I would appreciate reports of people who are using PCI or VESA network
cards with FreeBSD, specifying the brand and model, and benchmark results, if
available.

Thanks in advance. If I get any reports (I hope so :-) ), I will post a summary
here, just in case there are other people in the same situation.
