Re: 10GB Ethernet Cards

The only drawback i found on this list's archives is that if you are
low on ram, this attribute is for EACH connection made to the system,
so 64+64k per connection you could swamp the RAM of a little system
(talking about the systems of old that had 128mb or so ram).

64,384 sounds like somebody forgot their 64x1024 tables. It should be
65535 so it lands on a page, but i dont know if the i concerns itself
with memory fragmentation....

Best Regards,

Actually,
the defaults (on 7.1) are 65,535 (64K), and I have mine currently set
at 64,384 (I have no idea why that number).

ye olde chgtcpa and transmit receive buffer sizes? up to v5r4 at least
it always comes with 8k and ftp uses that value... change it to 16, 32
or more (mileage may vary) and voila net bottleneck vanquished... My
experience is only on power5 and older systems but it may apply

You'll hear a lot about:

looking at the Disk Arm Util (max) for those time periods, I see we get
to 30 to 35%, so we have a bit to gain there...
