[squid-users] Squid Box Tunning

I am running squid 24S1 on RH Linux 6.2 kernel 2.2.14-5 and it is quite
stable, my cachemgr ' Info ' look like this under heavy loads, i am running
transparent proxy through policy routing on Cisco , using ' diskd ' as store
type.
I need to know somethings from the following output:

1- My number of requests per minute is 1219.9 , can it be improved in any
way?
2- My counters for select loop called is i think ' High ', i have read the
Henrick's reply that it happens under bad transparent setups, how it can be
improved?
3- I have also read that number of requests/sec can be reached upto 100 with
a well configured Squid box, i need to know how can i reach this and what is
i am missing in order to achieve this?
4- Are the hit ratios fine or lower?

My ' df -h ' output looks like this:
Filesystem Size Used Avail Use% Mounted on
/dev/sda6 1.4G 96M 1.3G 7% /
/dev/sda1 15M 5.7M 8.6M 40% /boot
/dev/sdb1 17G 3.5G 12G 22% /cache1
/dev/sda5 1.9G 1.3G 559M 70% /usr
/dev/sda8 13G 10G 2.1G 83% /var
/dev/sdc1 34G 23G 8.7G 73% /cache2nd

My squid box is PIII 650, with 1 GB RAM , Ultra SCSI 10K rpm drives (Three
18GB IBM+18GB IBM+36GB Seagette Cheetah).

Any suggestions to improve my box , if you need any other info i am ready to
provide. I have also read Joe's article on tunning Squid boxes at
swelltech's website.
Thanks to all ' Squid Guru's ' on providing a very good support to
squid-users.
