Anyone working on PFS3 ??

[SHADES]

Just wondering if anyone is working on PFS3 to enable big TB partitions for big fast drives etc.....
Just such a shame if it has now been released and no one is interested. Such a great FS.

Currently almost all changes are generic. Of course the OS3 version is directly benefiting from the changes being made. There's only one SVN tree that has everything. Assuming the file system is ported to AROS and OS4 it'd be highly desirable to have those changes in the same SVN as well.

Anyone wishing to contribute should contact mr Pelt over sourceforge.

Very glad to to see porogress Piru.Tell michael to fix the donate button on the page.

SFS stops being fast when admin blocks are cluttered over the disk. Performance degrades faster if you are using .recycled directory but reality is that newly formatted SFS disk is always faster than old empty SFS disk.

Just for interest sake.

Some performance stats testing I did on newly created, freshly formatted partitions on my A4000 FastlaneZ3 SCSI equipped PC.

SFS should be at its fastest this way. PFS still kills SFS in speed.
