Hi Willy,
I have take a look about the last test on
http://haproxy.1wt.eu/10g.html
and thought it would be nice to see a test with the brand new 1.5
version.
What do you think ;-)?
I agree in principle, but you know, running benchmarks takes a *lot* of
time. The main issue I'm having right now is that I don't have a 10Gb
switch, so I'm running with direct-attached machines, with only one
client, one proxy and one server. In such a setup, it's common to see
all 3 machines at 100% CPU during some tests, and it's hard to tell the
part caused by client, server or proxy. The worst case I had was to be
limited to about 15 Gbps full duplex and not being able to determine
which machine or NIC was causing this, as most PCI-e chipsets I've
encountered in the past were not able to reach the line rate.
I really need to build a lab with at least 5 machines (2 clients, 2
servers, one proxy and a switch). This is the only way to measure the
impact on each component.
Anyway, what I'm expecting from new 10G runs with 1.5 is to have the
same data rate over the wire (since we're doing nothing for this, we
just use splice() to ask the kernel to do the work for us), but see an
increase in the amount of peak connections per second. This is
especially important for systems dealing with DDoSes using
stick-tables, as they need to get rid of a connection as soon as
possible.
Well you are right.
I'a just a benchmark junky and haven't such a equipment her so I thought
you or someone on the list maybe have the possibility.
Well it was just for my curiosity.
