PFS3aio vs SFS/02
Hello Toni, I tried to use pfs3aio filesystem with OS4.1, installation and successful, I wanted to ask, but its speed and lower than sfs / 02 or something wrong.
I always read that psf was much faster than sfs thanks to a possible reply |

Simply because SFS is PPC native but PFS3 is m68k-only? (becomes "double" emulated)

Toni thanks for the answer, I think it takes a more powerful PC for 4.1, I'm trying in every way :-)

Does SFS support other sizes than 512 bytes? I used to see a speed-up on PFS3 when I upped the block size to 32k on my classic Amiga.
Also SFS is unbearably slow in deleting on my MOS mac-mini. I finally bit the bullet and replaced it for PFS3. It is sooo much faster now in compiling stuff where tmp dirs/files are created and deleted. |

If you want fast deleting you have to format the partition without ".recycled" or ".deldir" directory. Add a lot of buffers is also a good idea. |

Regarding blocksize..what happens if you put anything above 1024 in there? Because my 15+ year old PFS(3) partitions didn't get the message that 8k, 16k, 32k (which I have some set at) are not supported. Or are those settings dummies and behind the scenes it is actually 512 bytes whatever the setting? |

Did I quick test and copied a 1 byte-sized file to a partition which had 8192 as block size setting and it actually took up 512 bytes.....LOL didn't know :-)

The filesystem (SFS and PFS3) limit the max block size internal. So it doesn't make sense to set higher values then 1024. FFS is different in this case. It will take what you have set (I don't know the max value).

Having a look at the picture you have provided, it seems that you have used the Normal DOSType instead of the DirectSCSI one for your 20GB disk.
Maybe it's correct, just double check with these extract from the PFS3_53 documentation (Aminet) : Quote:

Those descriptions (especially mask) are mostly obsolete. (Unless you have some old weird hardware like A2090..)
