Although this tweaking guide will help you figure out the (IMO) 'proper' settings for cacheman, it's still possible that it is still not the optimal settings for your system. You will still need to experiment with your own cache settings to achieve the best setting for your machine.

Just always bear in mind that the lesser the value you put in your "disk cache" the more RAM will be available for your programs/games, and will in turn improve their performance. BUT setting the "disk cache" too low, will degrade your harddisk performance. So 'balance' is the key in achieving the best setting for cacheman.

For the "chunk size", I recommend setting it at 1mb (1024). BUT you should also try setting it at 512kb and see if you will have better performance.

And as for the name and directory cache ... remember the time when you where still using that 'network server' tweak before cacheman took over the 'typical role' of your computer? The network server setting for the name and directory cache is 2729kb and 64kb respectively. But cacheman's default is slightly lower than that. So I recommend setting it the same as to what 'network server' had before.
