Do you mean cache memory, or disk cache?
If you mean memory (RAM) and you have enough of this in your system (eg: 32
Gbytes or more), then find the section in squid.conf which starts with:
# MEMORY CACHE OPTIONS
And read about the tag "cache_mem".
To set this value (normally 256 Mbytes) to 20 Gbytes, set:
cache_mem 20 GB
If, on the other hand, you do not mean memory, but you mean disk cache, then
find the section in squid.conf with starts with:
# TAG: cache_dir
and read that section.
Pay particular attention to the line which says:
# cache_dir ufs Directory-Name Mbytes L1 L2 [options]
And then later there is an example:
# cache_dir ufs /var/spool/squid3 100 16 256
Uncomment that line and change the 100 (Megabytes) in that line to 20000 (for
20 Gigabytes) and perhaps also adjust the 16 to something like 64 or even 256
- for a large cache you don't want a few directories with lots of entries
each, so it's worthwhile creating lots of directories to keep the number of
files in each down.

What do you mean by "performance"?
