Hi,
There was an issue at RAL T1 where they are trying to use proxy server
as their nodes do not have outgoing connectivity.
Trying to reproduce this at UCSD, I have been running test on a proxy
server without any caching using the following configuration file:
http://uaf-2.t2.ucsd.edu/~alja/onlyproxy.cfg
On the plot http://uaf-2.t2.ucsd.edu/~matevz/tmp/traffic.png is network
traffic of the proxy server during four consecutive tests:
- 300 jobs reading 2.4MB every 10s in 128 chunk-vector-read
- 300 jobs reading 2.4MB every 10s in a single read
- 150 jobs reading 2.4MB every 10s in a single read
- 150 jobs reading 2.4MB every 10s in 128 chunk-vector-read
Is there something obvious that we missed in the configuration of
proxy-only server? How should we go about trying to find the bottlenecks
here?
Thanks,
Alja
