Hi,

I am performing some basic performance tests with Traffic Server with and
without a plugin I have written. I have noticed that if you download
(without any plugin enabled) a file then download another file that the
second download is a lot slower that the first one - over 10 times as slow.
If you then wait for about 10-20 seconds it is back to the original speed.

For example downloading an 8MB file using wget takes about 0.09s, but
downloading the same or another 8 MB file on the same server again it is
1.3s. If I bypass the proxy then the files always downloads at about 0.07s.

This seems to be affecting the overall performance of Traffic Server. Note I
am using version 3.0.0 with no caching enabled.

Has any one got any ideas?

Thank-you,

Chris Reynolds.
