WHAT: NBLUG SPECIAL EVENT TOPIC: ReiserFS with special guest Hans Reiser WHERE: O'Reilly and Associates, Sebastopol WHEN: July 2nd, 2002 @ 7:30PM RSVP: http://www.nblug.org/rsvp/ ---- Hi there, everyone! We've got a very special meeting just added to our calendar. We're very lucky and happy to have Hans Reiser, who is the primary architect, the project manager and a programmer for the ReiserFS Project, coming to speak on July 2nd. This meeting falls outside of our normal meeting time (the 2nd is the first Tuesday, rather than the second Tuesday), which means we'll have two meetings in the month of July! For those who may not be completely familiar with ReiserFS, check out http://www.reiserfs.org/. Here is a short synopsis I grabbed from their website: ReiserFS has fast journaling, which means that you don't spend your life waiting for fsck every time your laptop battery dies, or the UPS for your mission critical server gets its batteries disconnected accidentally by the UPS company's service crew, or your kernel was not as ready for prime time as you hoped, or the silly thing decides you mounted it too many times today. ReiserFS is based on fast balanced trees. Balanced trees are more robust in their performance, and are a more sophisticated algorithmic foundation for a filesystem. When we started our project, there was a consensus in the industry that balanced trees were too slow for filesystem usage patterns. We proved that if you just do them right they are better--take a look at the benchmarks. We have fewer worst case performance scenarios than other filesystems and generally better overall performance. If you put 100,000 files in one directory, we think its fine; many other filesystems try to tell you that you are wrong to want to do it. ReiserFS is more space efficient. If you write 100 byte files, we pack many of them into one block. Other filesystems put each of them into their own block. We don't have fixed space allocation for inodes. That saves 6% of your disk. Due to the potential popularity of this meeting, we're asking folks to RSVP to let us know how many are coming. If we get enough folks, we might have to move the meeting to a larger facility (possibly SSU), so please, PLEASE RSVP as soon as you can.
