Hi!
Strange results - SFS shouldn't be that much slower. Now okay, here
are my test results. Note: Results may be vary on different platforms.
The following are tests I performed for my filesystem comparison
article in german Amiga print magazine "Amiga-Magazin". I have no
complete comparison on 68060 yet. I didn't only test speed but also
size occupation.
Machine was: Amiga 4000 CyberStorm 68040/40 and a 1GB IBM SCSI disk.
Well thats getting off-topic now.

The following tests are performed:
1) DiskSpeed + looking at Meter for the CPU time
2) deleting the following file and measuring the time:
Messagebase.BM ----rwed 27210016 Samstag 12:10:42
3) measuring the size occupied directly after formatting the disk
4) copying env: and measuring the size occupied by the directory:
env: 541.70 Kilobytes [Files: 821 Dirs: 77]
5) 3 + 4 = complete space occupied
6) delete all files and measure occupied space again
only SFS:
7) 6 - 3 = administration space that was occupied from SFS

3) PFS2 says 0K occupied, but it doesn't tell what is occupied as
internal admin space. But every volume has a certain number of
blocks, look at the DiskSpeed output for PFS2:
Volume Test: 57715 blocks (28 MB), 512 bytes per block.
FFS has 63248 blocks on the same partition, SFS one less.
So goes:
63248 - 57715 = 5533 blocks / 2 = 2766.5K!
This is about 10% of the partition size! On larger partition PFS2 V4.2
should only take 3%.
4) 825K
5) 2766.5 + 825 = 3591K
6) 2766.5K
c) FFS, 1024 byte per block
