Please optimise speed of Samba configuration

[steven@…]

Tested on Fonera 2.0g; it's almost impossible to use .mkv's on a fonera 2.0 and play it on a remote media player if these files exceed 700mbyte (it takes 5 minutes before the video starts playing).... mkv's are popular for those wanting to use FULL HD movies/series.

secondary problem related to this : any tweaking to the samba.config to improve the speed is being nullified after +- 5 minutes... the fonera tries to restore the original config nullifying our improvements.

We created a cron that restores our samba improvements every 5 minutes:

it would be welcome if you could configure this samba configuration by default in the next firmware release

#!/bin/sh

if ! grep SO_RCVBUF /tmp/smb.conf > /dev/null then

sed -i "s/TCP_NODELAY/TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=1024000 SO_SNDBUF=1024000 SO_KEEPALIVE/" /tmp/smb.conf sed -i "s/\/etc\/samba\/smbpasswd/\/etc\/samba\/smbpasswd\n deadtime = 15\n getwd cache = yes\n lpq cache = 30/" /tmp/smb.conf

This looks interesting, we'll look into this. Any comments on why these options help and what they do exactly? I'm particularly doubtful about the buffer options, since allocating 2x 1MB of buffers (for each connection?) might be a bit much for the 2.0g. OTOH, the original poster has had succes with this on a 2.0g.

I guess he read the Samba Tuning appendix:  http://oreilly.com/catalog/samba/chapter/book/appb_02.html the commands are explained in this chapter : "B.2.2.2 Socket options"

Yes I have to wait for the FON moderators to get my questions to the original person posted :-)

(In [1726]) Tune Samba configuration, fixes #866

[anonymous]

SO_XXXBUF values are way too high in your proposal, its hard to find a good default for all networks so it was not included.

This patch was applied only to the RestartSamba? and not to ReloadSamba?, so it is still not fixed properly

[matthijs]

I noticed this as well when diffing the two scripts (and I've already prepared a patch to fix it). Thanks for checking as well, though!

(In [1864]) samba: Apply r1726 to RestartSamba? script as well.

This tunes the samba configuration a bit, but it was only applied to the RestartSamba? script, not the ReloadSamba? script (making these performance tunings disappear when an USB disk was plugged in or out.
