Justin T. Gibbs	1a451e33ef	LFS stability patches. There is still a problem with directory update ... ordering that can prove fatal during large batches of deletes, but this is much better than it was. I probably won't be putting much more time into this until Seltzer releases her new version of LFS which has fragment support. This should be availible just before USENIX.	1995-01-04 23:46:34 +00:00
Justin T. Gibbs	471e5fa096	John Dyson's patches (and a few from me too) to LFS to use a different ... buffering scheme and make it more in tune with FreeBSD's vfs_bio implementation. The filesystem seems fairly stable, but I wouldn't recommend it to anyone not willing to experience problems. This is very green code and has the limitation that YOU CAN ONLY HAVE ONE LFS PARTITION MOUNTED AT A TIME. What LFS is good for: Non fsynced writes FASTER THAN FFS Large deletions Increadibly fast Reads are a little bit slower than FFS right now, but that is a factor of how under optimized this code is. LFS should in theory perform at least as well as FFS under fsync (iozone) type loads, and this is what I'm currently working on.
