Performance of Sockets vs. TCP/IP connections on localhost?

2005-02-09 Thread Lasse Laursen
Hi all!
Simple question: What is fastest when doing a connection to a local machine? 
TCP/IP or connecting via the socket? the application is a ACL helper program 
under Squid which makes a persistent connection to the database (100 
parallel programs runs on the machine each connecting to the MySQL database)

From the Connector/J documentation:

Named pipes only work when connecting to a MySQL server on the same 
physical machine as the one the JDBC driver is being used on. In simple 
performance tests, it appears that named pipe access is between 30%-50% 
faster than the standard TCP/IP access.
