How and where can one add directory cache to a HDD partition ? I know the FastFileSystem has the option to use something called directory cache, but there is no option to set the amount of it. Also it is not recommended to use the directory cache option because it is quite unstable.
You should rather add some buffers to the hdd partition. The default is 80 which is quite small. Use 200 or 300 buffers. And use a block size of 1024 (default with OS3.9's HDToolbox). But note that each buffer needs one block of memory (so 300 blocks of 1024 bytes needs 300kb of memory).
If you really want a speed up, you shouldn't use the standard FastFileSystem but rather PFS3 or SFS, which make the boot process really faster.
Well, changing the file system and the block size will destroy the data. Adding buffers is harmless.
