Having spent sometime benching Linode and Digital Ocean, I wanted to see what one of the often talked about favourites was about. I’m not going to write a lot as I believe the results speak for themselves. I’ve added some more of the historic data I had from previous tests as I may use this spreadsheet if I review any other VPS solutions in future.
Ramnode is coming in at around $15 per month (with online voucher), gives Linode a run for its money whilst being slightly cheaper. You still can’t beat Digital Ocean for performance per pound/dollar though.
All the data below as usual.
