RE: is IPC really faster than TCPIP?

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
