Incorrect throughput being seen in report and differing PGL configs

Hello,
I am using Web Polygraph version 4.4.0 and running against a proxy
server using 8 clients and 8 servers. After the report is run I see the
following data.
label: Tue Aug 2 13:52:51 BST 2011
throughput: 4196.00xact/sec or 608.43Mbits/sec
response time: 49msec mean
hit ratios: 18.86% DHR and 6.88% BHR
unique URLs: 820565xact (35.40% recurrence)
errors: 0.00% (8xact out of 1270224xact)
duration: 5.05min
start time: Tue, 02 Aug 2011 12:53:18 GMT
workload: available
Polygraph version: 4.4.0
reporter version: 4.4.0
however when I am looking at the switch statistics the number reported
is much lower (360Mbits/sec)
Could you clarify what the throughput value actually relates to?
I am also seeing the following message when trying to run the
polygraph-reporter. Could you help so that I can avoid this error?
PGL configuration in /opt/stress/scripts/tmp/sss-101-strs_1312291541.log
differs from the one
in /opt/stress/scripts/tmp/sss-103-strs_1312291541.log
All the configs are identical apart from the "use" line at the bottom
which I generate to pair up my servers and clients. The attached file
192.168.29.101.polygraph.pg is an example of this line. Each pair of
server / client will have the same line but the next pair will have a
different line.
Attached are my polygraph files to help you understand my setup.
Please let me know if you require further information or clarification.
Thanks in advance.
