De Kattenfabriek
>Environment:
System: FreeBSD cat.berkvens.net 4.10-STABLE FreeBSD 4.10-STABLE #4: Sun Oct 31 01:46:30 CEST 2004 sven@cat.berkvens.net:/extra0/usr_obj/usr/src/sys/CAT i386
>Description:
The port net-p2p/btqueue exhibits extremely slow file reads when
rechecking files for hash correctness and also in other situations.
This is due to a broken libc on FreeBSD 4.x, that does unbuffered
reads PER BYTE instead of filling a given buffer with one read call.
>How-To-Repeat:
Install BTQueue on FreeBSD 4.x and try to check existing torrents.
>Fix:
The following patch, when installed as
/usr/ports/net-p2p/btqueue/files/patch-BitTorrent::defaultargs.py
will solve the problem:

+++ BitTorrent/defaultargs.py Fri Mar 31 15:02:39 2006
