Speeding up Linux disk encryption (Cloudflare)

([Kernel] Mar 25, 2020 14:29 UTC (Wed) (corbet))


The Cloudflare blog has [1]an article on the company's work to improve the performance of Linux disk encryption. " As we can see the default Linux disk encryption implementation has a significant impact on our cache latency in worst case scenarios, whereas the patched implementation is indistinguishable from not using encryption at all. In other words the improved encryption implementation does not have any impact at all on our cache response speed, so we basically get it for free! " Patches are available, but they are apparently not in any form to go upstream.

Excerpts From The First Annual Nerd Bowl (#5)

A commercial that aired during the live ASCII broadcast of the game:

Having trouble staying awake for weeks at a time working on that latest
hack? Worried that some young punk will take over your cushy job because
you sleep too much? Don't worry, EyeOpener® brand cola is here to save
the day. You'll never feel sleepy again when you drink EyeOpener®.

Surgeon General's Warning: This product should only be used under a
doctor's immediate supervision, as it contains more caffeine than 512
cases of Coca-Cola.

Caution: When sleep does occur after about three weeks, optometrists
recommend having someone on hand to close your eyelids.

Coming soon: ExtremelyWired(tm) cola with 50% more sugar! May or may not
meet FDA approval... we're still trying.
