Speeding up Linux disk encryption

  • In Russian

Encrypting data at rest is a must-have for any modern SaaS company. Modern hardware has made encryption fast enough and not resource intensive. However, when using built-in transparent encryption on Linux based on LUKS/dm-crypt, it was noticed that read/write performance is far from expected. Cloudflare decided to investigate this issue and this report presents a patch that accelerates the speed of reading/writing data from encrypted disks on Linux at least 2 times.
