[squid-users] How to improve Hit Ratio

Hi all

I'd like to ask you how can I improve my Hit Ratio ( byte or request )
cause it's on average 12-15 %, so it seems too low

I'm using cacti to measure squid snmp activites and my basic config is:

RAM: 1 GB
cache_mem 8 MB
maximum_object_size_in_memory 1 MB
cache_dir ufs /var/cache/squid 5500 16 256
minimum_object_size 0 bytes
maximum_object_size 4194304 bytes
cache_swap_low 90
cache_swap_high 95

refresh_pattern windowsupdate.com/.*\.(cab|exe) 4320 100% 43200

refresh_pattern download.microsoft.com/.*\.(cab|exe) 4320 100% 43200

refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i \.(gif|png|jpg|jpeg|ico)$ 10080 90% 43200

refresh_pattern -i \.(iso|avi|wav|mp3|mp4|mpeg|swf|flv|x-flv)$ 43200 90%
432000 override-expire ignore-no-cache ignore-private
refresh_pattern -i \.(deb|rpm|exe|zip|tar|tgz|ram|rar|bin|ppt|doc|tiff)$

refresh_pattern -i \.index.(html|htm)$ 0 40% 10080
refresh_pattern -i \.(html|htm|css|js)$ 1440 40% 40320
refresh_pattern . 0 40% 40320

I'm hosting about 30 clients.
FQDNcache Entries: 362
FQDNcache Requests: 25181
FQDNcache Hits: 15192
FQDNcache Negative Hits: 5348
FQDNcache Misses: 4641

IP Cache Statistics:
IPcache Entries: 920
IPcache Requests: 497622
IPcache Hits: 332614
IPcache Negative Hits: 1088
IPcache Numeric Hits: 23602
IPcache Misses: 140318

Is it possible ot reach higher hit ratio ?

Thanks
