Does IPC help performance?

Some questions about ipc:

1. What is the bad effect after removing ipc from listener?
2. When select * from v$system_event, at "rdbms ipc message", the value of TOTAL_WAITS and TOTAL_TIMEOUTS are nearly same and high, is it a problem?
3. Do internal process or background process use ipc if available?

Configuration:
Oracle 7.1.6 NCR Unix 512MB RAM

Thank for any advice,
River
