After I upgraded to Ogra, I noticed that my server’s load stats were a little janky. They were pretty high, actually, bouncing between .5 and 2 all the time. Now this isn’t really all that bad, but as I looked at my server, I realized I was paying a little more than I needed, since I’d cut down on space by offloading backups better.
This matters because I needed only 50G of diskspace (I only use about 30 right now for all the sites), and while I did want 2G of RAM, I could easily switch to an SSD on my hosting plan. It was cheaper, and it was as easy as pressing a button. I’ve never really gotten to play with SSD for this site, so I thought “what the hell” and pressed the button.
A weekend later…
The five minute load average shows a massive drop. It’s incredible. The red and blank spots are where I was running the actual migration process and disabled monitoring for a bit. Literally all I did was reboot the server and the move it to SSD. That’s it. It’s insane when you think about it.
By the way, I saved disk space by offloading the backups to Amazon S3. Amazon costs me about $3 a month, and while I detest their interface, the integration is built into WHM. I have an open feature requests to allow arbitrary CEPH destinations as backup so please vote for that if you like the idea.
SSDs had the bonus of changing my backup from taking 2 or 3 hours to taking 15 minutes.
Anecdotally SSD is an incredible improvement of the old bog hard drives.
