You need to use a more efficient implementation. Why do you need a
UNIX-domain server in the first place? Have you considered the
following:
- You can specify MULTIPLE maps in the transport_maps parameter
value. Specify a hash: map (for easy lookups) before other maps.
- PCRE tables can do the pattern matching without sending things
across a socket and doing pattern matching in a different program.
- Use a persistent server. Do not use fork() or exec() or system()
for every query.
