In the note I sent a few hours ago, I mentioned a 50x number. This is = what
we saw one place. Your mileage may vary, but it's easy to test. You can = test
your raw IPC vs TCP/IP performance by writing a small test in sqlplus = that
makes a million database calls. Time a run of it connected through an = alias
where PROTOCOL=3DIPC. Time another run of it connected through an alias = where
PROTOCOL=3DTCP. Compare and contrast the results.

I'd be really interested in hearing the opinions of others on this - we = are
thinking of implementing IPC on the recommendations of Informatica (our = ETL
tool). We have a lot of network traffic due to the row-at-a-time = processing
in informatica.

Informatica and Oracle are both on the same box.

Hi list, Sorry for starting two thread about the same, but I found=20

Tom Kyte says "well, tuning TCP vs IPC would give you marginal = improvements.

but Kenny Smith in Use IPC for local connections, a process can be up to = 10x
faster
he says " I've seen a SQL job that runs in 10 minutes using TCP on a = local
machine run as fast as one minute using an IPC connection" But http://searchoracle.techtarget.com/originalContent/0,289142 sid41_gci940662,00.html
=20

So I think the question is not is why ipc is not faster, else is IPC = really
faster.
Some experiences please.=20
