Ramdisks and hard drives as cache devicesRamdisks and hard drives as cache devicesPosted Jul 22, 2010 20:59 UTC (Thu) by nix (subscriber, #2304)In reply to: Ramdisks and hard drives as cache devices by neilbrown Parent article: Bcache: Caching beyond just RAM
Unfortunately if you want to spot cache invalidations, the lack of leases on NFSv3 is a killer, because you still have to roundtrip to the server to see if your cache is stale, and roundtrips are the slow part :( fs-cache slows NFS *down* quite considerably in my experience, for exactly this reason.
