Re: Severe performance degradation on Linux

The following is interesting:

Pipe mode versus socket mode.  When I spawn LO to listen to a named pipe
instead of a localhost:2002 socket, then performance is dramatically
different on Linux:

On the remote Gentoo Linux server
Pipe mode: Elapsed time: 0.5140466690063477 with 550 pars
Socket mode: Elapsed time: 45.658066272735596 with 550 pars

On the local Ubuntu Linux machine
Pipe mode: Elapsed time: 0.8761096000671387 with 550 pars
Socket mode: Elapsed time: 45.715266942977905 with 550 pars

On my Mac
Pipe mode: Elapsed time: 1.941413164138794 with 550 pars
Socket mode: Elapsed time: 1.941413164138794 with 550 pars

This doesn't quite solve the problem of why using sockets on Linux is so
much slower, but it does solve the larger problem of having an efficient
connection from an UNO Py client to the office server.
