LiteSpeed Technologies has officially released version 4.1 of their web server software and with it comes full AIO (asynchronous I/O). It's a rather complicated feature and would be hard for me to explain to somebody familiar with web servers in general.
Now I want to put how much of a benefit this new feature is into perspective... We recently had issues with our Cypress server where during R1Soft backups or cPanel backups all websites would become virtually unresponsive and I actually sent out an open letter to all customers on the Cypress server (read it here). We upgraded LiteSpeed to version 4.1 on the Cypress server and enabled AIO support and then we began testing the server to see what kind of effect the new AIO would have on site performance under heavy load.
Not only are we currently running a full R1Soft block scan of the server but we're also simultaneously running a cPanel backup of a rather large account and there is virtually no impact on site loading speed what-so-ever. This is an amazing development and we've rolled this feature out to all servers.
What this means for you:
- Backups can be performed any time, day or night, without dramatically affecting server performance. We do still however ask that you take your regular backups during off-peak times.
- That our daily R1Soft backups that protect your data against hardware failure and other forms of data loss will not impact your site performance.
If you have any questions at all about this, do respond to this thread
