I have uploaded the squid cache server to the Cacko Feed at:
http://cacko.biz/cacko/feed
It should give you a web browsing performance increase since none of the browsers included with Cacko do much caching. You will need a non-FAT formatted media card to store the cache on and some post install configuration documented in the help file.
You can find some additional info on Squid here.
Please let me know how it goes for you.
Thanks!
