Package: network-manager Version: 0.6.4-7 Severity: important
I noticed that all interfaces managed by NetworkManager seem to have an MTU of 576 bytes (the minimum). This seems to have a negative effect on download speed, or certainly not a positive one. As nm_system_get_mtu() in src/backends/NetworkManagerDebian.c returns 0, NetworkManager doesn't seem to set the MTU explicitly though, so I'm not sure where the default is coming from. I verified that hacking the above function to return 1500 results in interfaces managed by NetworkManager having an MTU of 1500, with a line like Apr 6 12:18:52 thor NetworkManager: <information>^ISetting MTU of interface 'sungem' to 1500 in syslog. --- System information. --- Architecture: powerpc Kernel: Linux 2.6.21-rc5 Debian Release: lenny/sid 500 unstable mirror.switch.ch 500 stable security.debian.org 102 experimental ftp.ch.debian.org --- Package information. --- Depends (Version) | Installed =================================-+-============= libc6 (>= 2.3.5-1) | 2.3.6.ds1-13 libdbus-1-3 (>= 0.94) | 1.0.2-1 libdbus-glib-1-2 (>= 0.73) | 0.73-1 libgcrypt11 (>= 1.2.2) | 1.2.3-2 libglib2.0-0 (>= 2.12.9) | 2.12.11-1 libgpg-error0 (>= 1.4) | 1.4-2 libhal1 (>= 0.5) | 0.5.8.1-9 libiw28 (>= 28) | 28-1 libnl1-pre6 | 1.0~pre6-4 libnm-util0 | 0.6.4-7 iproute | 20061002-4 iputils-arping | 3:20020927-6 dhcdbd (>= 1.12-2) | 2.0-3 lsb-base (>= 2.0-6) | 3.1-23.1 wpasupplicant (>= 0.4.8) | 0.6.0~cvs20070224-1 dbus (>= 0.60) | 1.0.2-1 hal (>= 0.5.7.1) | 0.5.8.1-9 ifupdown | 0.6.8 adduser | 3.102 -- Earthling Michel Dänzer | http://tungstengraphics.com Libre software enthusiast | Debian, X and DRI developer
