Remove default setting of "set txqueuelen to 100". This default dates back to the "pre git" times (before 2005) and might have been beneficial back then - nowadays, the Linux default is 500, and thus reducing(!) txqueuelen by-default can cause TX packet drops on the tun interface, and that's bad for throughput.
This is a similar change to commit f0b64e5dc (remove setting of the socket send/receive buffers by default) - similar vintage of the existing code, similar motivation. Note: buffer length can be checked with "ip link show" (qlen NNN) See also: https://ivanvari.com/solving-openvpn-poor-throughput-and-packet-loss/ Signed-off-by: Gert Doering <g...@greenie.muc.de> --- src/openvpn/options.c | 3 --- 1 file changed, 3 deletions(-) diff --git a/src/openvpn/options.c b/src/openvpn/options.c index c21ef56d..a40efd68 100644 --- a/src/openvpn/options.c +++ b/src/openvpn/options.c @@ -840,9 +840,6 @@ init_options(struct options *o, const bool init_gc) #ifdef ENABLE_FEATURE_TUN_PERSIST o->persist_mode = 1; #endif -#ifdef TARGET_LINUX - o->tuntap_options.txqueuelen = 100; -#endif #ifdef _WIN32 #if 0 o->tuntap_options.ip_win32_type = IPW32_SET_ADAPTIVE; -- 2.26.2 _______________________________________________ Openvpn-devel mailing list Openvpn-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-devel
