past 48Mbps. Did notice it was routing through Ashburn, which is less

Re: [WISPA] One connection bandwidth=x / 2 commections bandwidth=2x why?

2009-05-11 Thread Tom DeReggi 
When this occurs it usually means that your connection has minor packet loss 
or TCP delays in transfer, very hard to identify. You will likely find that 
UDP will transfer full speed.
TCP is doing what it is supposed to do, which is slow down, to attempt to 
correct congestion, but in reality may be caused by transmission delays.

Here are two things that can cause random sporatic delays in transmission.

1) Switches with Flow control on. (should be turned off).  I recently had 
transmission increased from 3-5mbps to 24mbps on a path, simply by disabling 
Flow control. (Flow control really only meant to be used on switch when 
connected directly to an end user PC, not a backbone connection).  This can 
be common, because many switches default with flow control on, and its 
something you can't check yourself, if its at your upstream first hop.

2) Bandwidth management on hardware with inadequate timers, and high traffic 
load.  (If Linux, should be using kernels 2.6.21 or higher, for 
high_res_timers, if high speed links).

3) Basic hardware failure.  A flaky NIC port. A Bad cable. Wrong NIC Driver. 
Actually Resulting in very small amounts of packet loss or sporatic 
transfer.

4) TX Buffers to low. Or other similar NIC driver optimization. I think 
Linux defaults to 100, but for Gig_e should be like 1000. Should check 
optimization suggestions for your specific brand NIC. Those are the kind of 
things that might show failures when testing under load, but where there is 
free capacity on link still.

5) Window size incorrectly adjusting.  Manually test with hard set window 
sizes, to compare results.

You can sniff at layer2, to see if there are excessive acks or 
retransmissions, which sometimes can be an indicator that something is 
wrong.

Should also be noted whether problem occurs both with significant other 
traffic on connection, or if no other traffic passing when testing.

Timing delays are accumulative, and small individually, so they often can't 
be identified at a device easilly, by testing a single hop or link 
individually.

We ran into something like that when a customer was using his laptop to
generate traffic on a frac DS3 circuit.  The issue was primarily due to how
his application was trying to generate traffic.

[WISPA] One connection bandwidth=x / 2 commections bandwidth=2x why?

2009-05-10 Thread Scott Carullo 

On our main upstream connection 100mb fiber a speedtest to BHN yeilds about 
7MB max when 15 is there...

Open two connections tcp and now the transfer rate doubles (from same 
server to same client).

What would cause this?
