High Performance Data Transfers

High Performance Data Transfers

Post by Breen Ouellett » Tue, 01 Feb 2000 04:00:00


    I am trying to find out how to optimize the kernel for high
performance data transfers.  As a point of reference, under NetBSD one
can change these options in the kernel config file:

options         SB_MAX=1048576          # maximum socket buffer size
options         TCP_SENDSPACE=65536     # default send socket buffer
options         TCP_RECVSPACE=65536     # default recv socket buffer
options         NMBCLUSTERS=1024        # maximum number of mbuf

    Where do I find the equivalent settings in OpenBSD?

1. High Performance Data Transfers

There is a very nice multi-platform document on "High Performance Data Transfers"

Most of the data for Linux is missing :(
I reported the only item I know (Path MTU discovery) to the author.

There are still 4 blank items...

Perhaps some kind Linux networking guru can take a look.

Thanks, Richard.
