[K12OSN] Fedora Tweaks?

[Joseph Bishay]

Hello,

Just installed the K12Linux (Fedora 10 LTSP based) and I was just
following the various guides online to set up audio, video, etc.  I
came across this Fedora 10 guide
http://www.fedoraguide.info/index.php?title=Main_Page

In it were some tweaks for speeding up Firefox, Linux, etc and one of
the recommendations for bandwidth was as follows:

* Open the sysctl.conf file for editing and backup your previous
sysctl.conf file

su -c 'cp /etc/sysctl.conf /etc/sysctl.conf.backup'
su -c 'gedit /etc/sysctl.conf'

* Add the following lines

 ## increase TCP max buffer size setable using setsockopt()
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
 ## increase Linux autotuning TCP buffer limits
 ## min, default, and max number of bytes to use
 ## set max to at least 4MB, or higher if you use very high BDP paths
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
 ## don't cache ssthresh from previous connection
net.ipv4.tcp_no_metrics_save = 1
net.ipv4.tcp_moderate_rcvbuf = 1
 ## recommended to increase this for 1000 BT or higher
net.core.netdev_max_backlog = 2500
 ## for 10 GigE, use this, uncomment below
 ## net.core.netdev_max_backlog = 30000
 ## Turn off timestamps if you're on a gigabit or very busy network
 ## Having it off is one less thing the IP stack needs to work on
 ## net.ipv4.tcp_timestamps = 0
 ## disable tcp selective acknowledgements.
net.ipv4.tcp_sack = 0
 ##enable window scaling
net.ipv4.tcp_window_scaling = 1

* Save it and close it. Run the following command

 su -c '/sbin/sysctl -p'

Given that LTSP is a bit more complex than the usual network stuff,
would any of this help or hinder?

Thanks,
Joseph
