Real Quietly Releases More Code as Open Source

AlexJeff writes "Yesterday Real open sourced the server source code of its Network Optimized FileSystem (Asynchronous FileSystem). Actually it "dual-licensed" it under its open source (RPSL) and commercial licenses. According to a posting on the Helix Community, the Asynchronous FileSystem provides asynchronous access to the OS file-system and is mainly used to help resolve timing issues with Network File System(NFS). This functionality provides improvement capacity in 'Helix DNA-powered servers, especially on frameworks that use Network File System.'"

Re:What is this?

Good question -the project page doesn't say either.

From the context clues, I'll take a guess - NFS performance is OK if you use the async mount option. But then you risk data loss. The Linux NFS devs tell you never to use async mode. So you use sync mode and then the performance sucks (3.5x slower in the tests I did a few years back).

So maybe this provides a safe async filesystem. That would be nice, especially if it's easier to setup than OpenAFS.

Still it would be helpful if they had a WTF page. Maybe they do and I didn't find i t.
