After using these settings, squid is faster than before, but still
slower than Apache.

Try this:
grab Squid-2.HEAD from http://www.squid-cache.org/Versions/v2/HEAD/
install a somewhat recent Linux version
Configure Squid with a reasonably cache_mem, a null cache_dir and
reasonably sized maximum_object_size_in_memory settings for your
content.
Example:
cache_mem 128 MB
cache_dir null /null
maximum_object_size_in_memory 1 MB
Regards
Henrik
