CloudFlare CDN Available Now on all cPanel Hosting Plans – Free

CloudFlare Railgun™

CloudFlare Optimized Partner

As a CloudFlare Optimized Partner, we are thrilled to offer the CloudFlare Railgun™ technology to all our customers free with any hosting package! Railgun is CloudFlare’s latest performance optimization technology that gives you significant improvements in site load times. To activate Railgun, log into your cPanel and select Railgun “On”. Read on for additional details and instructions:

Railgun ensures that the connection between our network and the CloudFlare network is as fast as possible. Railgun achieves a 99.6% compression ratio for previously uncacheable web objects by using techniques similar to those used in the compression of high-quality video. The average website can expect a 1.43x performance increase.

When a request is made to a CloudFlare server for a web page that is not in cache CloudFlare makes an HTTP connection to the origin server to request the page. It’s that HTTP connection that Railgun accelerates and secures.

Even highly dynamic websites change slowly

Railgun works by recognizing that uncacheable web pages do not change very rapidly. For example, during an experiment, the CNN.com homepage HTML was captured once, and then again after 5 minutes and then again after one hour. The page sizes were 92,516, five minutes still 92,516 and one hour later 93,727.

CNN sets the caching on this page to 60 seconds. After one minute, it is necessary to download the entire page again. However, loo

king inside the page, not much has changed. In fact, the change between versions is on the order of 100s of bytes out of almost 100k. Here’s a screenshot of one of the binary differences between the CNN home page at five minute intervals. The yellow bytes have changed, the rest have not.

Experiments at CloudFlare have revealed similar change values across the web. For example, reddit.com changes by about 2.15% over five minutes and 3.16% over an hour. The New York Times home page changes by about 0.6% over five minutes and 3% over an hour. BBC News changes by about 0.4% over five minutes and 2% over an hour.

Although the dynamic web is not cacheable, it is also not changing quickly. That means that from moment to moment there’s only a small c

hange between versions of a page. CloudFlare Railgun uses this fact to achieve very high rates of compression. This is very similar to how video compression looks for changes from frame to frame; Railgun looks for changes on a page from download to download.

Railgun Technology

Railgun consists of two components: the sender and the listener. The sender is installed at every CloudFlare data center around the w

orld. The listener is a software component that [Name of Hosting Provider] has installed on our network for customers.

The sender and listener establish a permanent TCP connection that’s secured by TLS. This TCP connection is used for the Railgun protocol. It’s an all binary multiplexing protocol that allows multiple HTTP requests to be run simultaneously and asynchronously across the link. Or in other words, a persistent connection is opened between CloudFlare’s network and ours and eliminates the overhead of TCP.

We have made it simple for our customers to get the benefits of Railgun with one click.For additional information or questions please open a support ticket.

ownCloud One-Click Install from SolusVM on OpenVZ VPS Accounts

ownCloud One Click InstallDue to popular demand, we have created an OpenVZ OS template based on Centos6 x86_64 that has ownCloud v 4.5 installed with a default version of Apache, PHP5 and SQLite.

Current, or new users can select this template from SolusVM under the “Re-Install” tab. Once completed, all you need to do is login via ssh, start Apache with “service httpd start” command and point your browser to the IP address of your VPS.

Some of the benefits of hosting your own cloud for files (like ownCloud) include:

  • Full control of your files
  • Secure server which you have root access to
  • Privacy
  • Eliminate DropBox
  • More professional
  • Keep your digital rights to photos

What does ownCloud allow me to do?

For starters, you can use it as a secure replacement for DropBox, and you can even password protect the URL’s you send to other users in-case the file is sensitive in nature.

You can upload any kind of file (up to 512MB per file) and access it from the web, through WebDAV, the ownCloud iPhone App, and the Mac OS X/Windows Desktop App.

It is a music player and video streamer (with supported addon enabled).

Bottom Line

You can have full control of your files, share them with your friends or collaborate with your clients if you are a small/medium business owner in a very simple tool.

The benefit of using it on an OpenVZ.ca based VPS, is that you can scale resources as you grow. Start out with the Small VPS package and go beyond the storage of ExtraLarge as you need it.

Can I run Virtualmin with under 512mb of Ram?

One of the most popular trends we have been seeing at OpenVZ.ca as of late is the huge incoming flow of orders on which our customers are choosing Virtualmin GPL as their desired control panel. As an alternative to cPanel or DirectAdmin it has some advantages. The first and foremost is that it is free (There is a paid version with more features) and it accomodates the more advanced users giving access to such things as apache configuration files and named zone files.

So why am I writing about this? Well, majority of these new orders are placed with the most minimum VPS package we offer, “Small.” Weighing in at 128mb of ram and 2 CPU cores at 1.0ghz this configuration will create errors even before you try to run Virtualmin GPL.

In order to run Virtualmin GPL properly you will need a “Class A” supported system which is on the Virtualmin Website, and at a very minimum 512mb of ram.

RAM Usage on OpenVZ Virtualmin CentOS Fresh Installation

RAM Resources during/post Installation on CentOS 5 in OpenVZ

We have done some experimenting and the installation script will fail with errors unless you have approximately 490mb of ram available. This is on an OpenVZ VPS (XEN may be different).

At 512mb of ram, the installer will complete and you will be able to run the panel but when you go through the setup wizard do not select any options which require more ram or you will max out the guaranteed resources for your VPS.

In short, if you want to run Virtualmin GPL on a VPS do so with at least 768mb of guaranteed ram and if possible go for 1gb to accomodate for future growth. Always use a “Grade A” supported system and make sure that you scatter virtualmin’s default cron job’s throughout the day so that you do not max out all of your CPU time at midnight.
