Question

Is the RAM your paying for dedicated or burst?

  • Posted June 6, 2013

For example, on the lowest level plan you get 512mb, is the actual RAM 256mb with a 256mb burst?

Swapping on SSD will still be terrible, just not as bad as on spinning disks. RAM access latency is measured in single digit nanoseconds, SSD access latency is 50-100 microseconds, HD access latency is 11-20 milliseconds. So, SSDs are 200x quicker to respond than harddrives, but still about 10,000 times slower than RAM.

The Ubuntu article should work on Debian. We have another article for CentOS: https://www.digitalocean.com/community/articles/how-to-add-swap-on-centos-6

Ah, interesting option. How is swap performance on SSD? I imagine it’s considerably closer to that of actual RAM. <br> <br>Any instructions for CentOS / Debian?

Any bursting allowed?

All RAM is dedicated to your droplet. The kernel does take a bit of RAM so you’ll end up with ~490MB memory on the 512MB droplet.

Actual RAM is 512 Mb.
