It does not exist.
Squid-3 does proper memory-only caching by default. Just erase or
comment out all cache_dir lines in your config and it works.

RAM is faster than disk. This is a bast fact of I/O.
Eliminating the disk from the proxying system changes the I/O needs.
Whether that switch is a latency gain or loss depends on your traffic.
If your network is faster than the disks you were using; then it may
have some gain, otherwise not.
