Tennfy before the Linode Debian system. The article introduces the sharp speed, the effect of sharp speed is really very good, can effectively enhance the local to the VPS connection speed. However, the sharp speed in the KVM or Xen VPS Chinese can be used, for many OpenVZ VPS users is somewhat regrettable. This article is to introduce the sharp speed in the OPENVZ VPS environment Alternative –net-speeder.
Net-speeder Introduction
Net-speeder is a TCP accelerator similar to the sharp speed and has the advantage of not having the sharp speed: it can be used in OpenVZ virtualization VPS. However, the relative Yu Rui speed can be lost by the evaluation and prediction of packet loss, accurate estimation of path bandwidth and other means of intelligent contract, Net-speeder adopted a more simple and rough way, forced double contract. Such practices have pros and cons, the advantages of high delay in the unstable link (such as telecommunications to the United States VPS) can effectively reduce the rate of loss, but the double contract means that the cost of double flow, for the limited VPS traffic needs to be cautious.
Net-speeder GitHub Project Address: Https://github.com/snooda/net-speeder
Installation and use of Net-speeder
Installation of Net-speeder
Download the Net-speeder installation script after logging into the VPS
wget--no-check-certificate Https://raw.githubusercontent.com/tennfy/debian_netspeeder_tennfy/master/debian_ netspeeder_tennfy.sh
Execute the Script
chmod a+x debian_netspeeder_tennfy.sh
Bash debian_netspeeder_tennfy.sh
The use of Net-speeder
When the script is installed, the Net-speeder is run automatically. You can view the Net-speeder run status and stop Net-speeder by following these commands.
To see if Net-speeder is running
PS Aux|grep net_speeder|grep-v grep
Stop Net-speeder
Killall Net_speeder
Start Net-speeder (OPENVZ environment)
Nohup/root/net_speeder venet0 "IP" >/dev/null 2>&1 &
Set Net-speeder timer switch
Net-speeder is actually quite controversial, the double contract will lead to network congestion, a bit of a sense of beggar-thy-neighbour. As a result, TENNFY gives a tradeoff between opening net-speeder at the peak of the night and turning off the idle time.
1. Set time zone
Since the US VPS time zone is inconsistent with China, it is necessary to set the time zone for the VPS.
Execute the following command
echo "Asia/shanghai" >/etc/timezone
Enter the date command to see if the time displayed on the VPS is the same as local.
2. Set Net-speeder timing Switch
We set the 19-point open, 24-point off. Execute the following command:
Echo ' 0 * * * * root nohup/root/net_speeder venet0 "IP" >/dev/null 2>&1 & ' >>/etc/crontab
echo "0 0 * * * root killall Net_speeder" >>/etc/crontab
/etc/init.d/cron restart
Net-speeder Matters needing attention
The following situations are not suitable for use with Net-speeder:
1, the server traffic is small, because use Net-speeder will consume double flow.
2, mainly provide Web pages, pictures and other small file access. Net-speeder for downloading large files, proxy access to video sites and other effects are better, and small file acceleration effect is not obvious.
3, need to use pptpd and so on does not support the double contract the network software. Net-speeder can cause these software to not be used properly.
4, if the line itself is very good, there is no large delay, the use of net-speeder effect will backfire.
