How many buffers should I assign to each PFS-2 partition ?

The HDToolBox default of 30 buffers, actually 70, will result in poor performance. The minimum should be 100. The following values are recommended :-

    100 - Minimum
    150 - Normal partitions
    250 - Large directories (>2000 files)
    MAX - Very large directories (Web cache disks)

Increase these values if the partition is large.

Remember that each buffer is 1024 bytes and NOT 512 as is true for FFS.

AFS 2.2 (15.9) sanity checks the number of buffers ensuring that the value is between 50 and 300.

AFS 2.4 (16.16) sanity checks the number of buffers ensuring that the value is between 70 and 500.

PFS-2 4.1 (17.3) sanity checks the number of buffers ensuring that the value is between 70 and 600.
