>Synopsis: slow bm(4) network speed
>Category: macppc
>Environment:
System : OpenBSD 5.8
Details : OpenBSD 5.8-current (GENERIC) #657: Fri Aug 21 21:58:32
MDT 2015
[email protected]:/usr/src/sys/arch/macppc/compile/GENERIC
Architecture: OpenBSD.macppc
Machine : macppc
>Description:
Network speed on a local network is really slow when using bm(4).
>How-To-Repeat:
Put some files on another box, running httpd(8) or sthttpd, for
example.
Then, try to ftp(1) these files on a macppc having a bm(4).
Transfer speed will be really slow (around 0.3 KB/s), even
when forcing 100baseTX full-duplex.
>Fix:
Borrowing the following diff from NetBSD PR #33667 fixes the
problem for me (I'm getting 780 KB/s).
