Hi, I'd first give ZFS a shot - either through opensolaris or FreeBSD. It has slightly saner memory caching logic (which eats RAM for breakfast mind you) that may suit this workload a little better.
Since you mentioned ZFS, I have been thinking for some time now about deploying a Squid box with a ZFS cache either on a single drive or a separate drive.
Thats probably a smarter move than trying to squeeze a HTTP proxy inline just yet. :)
Do you think that this ZFS file system scales better than current file systems if used for caching such as Squid?
Do you have any statistics? Thanking you...

The problem is, that the "natural" caching of linux does not work, even if I have only arround 700 MByte of songs I hear all the time and the installed memory is 2 GByte. The access of gnump3d on the harddisk is very heavy, specialy if more then 4 clients use it the same time... -- and the Media-Server is working 24/7 and use already a Hardware Raid-1 with HotFix! What I like to do is to cache those files in a Ramdisk of 1 GByte and like to use squid-cache to do the "administration" of it, exactly, I want to CACHE and HOLD files with following rules: 1. most heared songs with highest priority (e.g. songs which are heared more then 20 times a week should never removed from cache) 2. if ram-disk-space is availlable all other songs and of course, the cached files should never expire... (the Media-Server is connected to a "bigger" 3000VA APC-Smart-UPS) Note 1: Since 1 GByte memories (DDR400) are availlable under 40 Euro I can add a third module... Can this be done with squid? Note 2: My Idea was already to put the "always heared" songs on a Infineon CF-Card of 8 GByte (arround 88 Euro) which is definitivly cheaper as replacing all 12 month a harddisk. Ideas?
