Re: SFS (68k) and recycled dir

What's more important if using only a few KB more for the SFS buffers makes it 10 or even 100 times faster?
10% cache misses is a lot, if you get more than 1% cache misses (after using the partition as usual for some time, don't check it for example directly after (re)booting) SFS is already much slower than it could be.

On classic Amigas with only a few MB RAM using enough buffers may not be possible, but on the AmigaOne, or a CSPPC with 128 MB or a BPPC with 256 MB RAM, it's not, you usually only need a few KB more RAM for the buffers of each SFS partition to get much faster speeds, not several MB.

Understood, though you don't say what would be a good
buffers setting for, lets say
256 MB
500 MB
1 GB
5 GB
10 GB
25 GB
70 GB

partitions...(that being my partition sizes)


About Raziel i still don't uderstand if he is speaking about AOS4 on AOne or Classic!

Check my extra info, i try to port stuff, thus needing every
byte of RAM i can get (until VMEM pops up )
