Could you pleas explain that numbers? I did almost the same test and found =
the=20
following values in MByte/s:
=46BSD 5.2 -> 5.2 / 4,6 (Client 1,1G Cel, Server C3 800)
Linux -> 5.2 / lockup (Client 733 PIII, Server C3 800)
=46BSD 4.9 -> 5.2 / 2,8 (CLient 233MMX, Server C3 800)
=46BSD 5.2 -> 5.1 / 6,5 (Client 1,1G Cel, Server C3 800)
Linux -> 5.1 / 9,8 (Client 733 PIII, Server C3 800)
=46BSD 5.2 -> 4.9 / 5,8 (Client 1,1G Cel, Server C3 800)
Linux -> 4.9 / 9,8 (Client 733 PIII, Server C3 800)
=46BSD 4.9 -> 4.9 / 3,0 (Client 233MMX, Server C3 800)
DragonFlyBSD as Server resulted in about 5% more performance than 4.9 (line=
ar=20
exept Linux Client as it performs with the maximum Ethernet Speed)
My tests were without modifying any rsize/wsize. But even with (rw)size 32k=
i=20
had expected to be able to transfer about 9 MByte/s from a 233MMX box.=20
3MByte/s is absolutely lousy. What hardware do we need for just tranfsering=
=20
bytes? 1GHz? I think 233 MHz with 64MB for OS should be more than enough.=20
Regrettably I haven't had time to install a Linux on the 233 box.
Btw. Linux =3D DebWoody (2.4.22) and all clients have fxp interfaces!
Summary: 5.1 as server was a lot faster than 5.2 as server so is 4.9. Faste=
st=20
was DragonFlyBSD but anyhow, just Linux as Client does a reasonable job. An=
d=20
not to forget the broken Linux -> 5.2 support!!!
