[PROBLEM] Increase network buffer

[Uncle_Tubbie]

Would this help, it's from IGOR blog:

A successor to compcache, zram, has been already integrated in the Linux kernel for a while now. This means that no additional compilation nor tweaking is required to benefit from compressing memory on the fly and massively reduced swapping.

As with compache, I wanted to nicely integrate the solution into the Ubuntu Upstart deamon – hence this short article. After a couple of minutes of playing the configuration was ready.

Create file zramswap.conf in /etc/init and put the following content in it.


01 description "Initializes zram swaping"
02
03 start on runlevel [2345]
04 stop on runlevel [!2345]
05
06 pre-start script
07
08 # load dependency modules
09 modprobe zram num_devices=2
10
11# initialize the devices
12 echo 1073741824 > /sys/block/zram0/disksize
13 echo 1073741824 > /sys/block/zram1/disksize
14
15 # Creating swap filesystems
16 mkswap /dev/zram0
17 mkswap /dev/zram1
18
19 # Switch the swaps on
20 swapon -p 5 /dev/zram0
21 swapon -p 5 /dev/zram1
22 end script
23
24 post-stop script
25
26 # Switching off swap
27 swapoff /dev/zram0
28 swapoff /dev/zram1
29
30 rmmod zram
31 end script
Now you can start the service with sudo start zramswap (it will be automatically started on after the reboot as well).
You will benefit from 2x1GB swap files, which will be compressed and stored in the RAM. Tested on Ubuntu 11.04.


PLEASE remember Im not the smartest guy in the room, so wait till someone else confirms this before trying at your own risk.
