       echo 0 > /proc/sys/vm/dirty_writeback_centisecs
       echo 60 > /proc/sys/vm/dirty_background_ratio
       echo 95 > /proc/sys/vm/dirty_ratio
       echo 0 > /proc/sys/net/ipv4/tcp_timestamps
       echo 1 > /proc/sys/net/ipv4/tcp_no_metrics_save
end script
Just add first 4 lines to be in sync with coding standards:

Code:
description "it is my own N900 tuning"
author "YourName"

console output
instead of ugly line started from # (sorry for that). And please - enclose any numeric value before '>' sign into double-quotes like

echo "95" > /proc/sys/vm/dirty_ratio

It could not expose you to very common bug - the sequence like '95>' without space has a special meaning in shell.

Note: I didn't evaluate the effect of that "echo" commands.
