Subject Re: simultaneous socket connections per server when downloading components for a page.
Date Tue, 02 Nov 2010 13:16:31 GMT
Hi Deepak,

to answer both your concerns:

1. Yes, it does even out. In the case of real users, requests will arive
in "groups" of, say, 8 parallel requests, but your server still has to
service them. 100 clients on a page with 20 embedded resources will make
2000 requests. The fact that real users do them in parallel matters
little. To the servers, there are far more requests than it can actually
handle in parallel, so serialization *will* happen.

To put it differently: Given enough threads, the server sees high
parallelism in requests, and there is no need for the client to try and
introduce a "higher" degree of parallelism. The server won't notice a
difference.

2. Please see the earlier thread. Deepak Shetty explained in-depth why
Jmeter (nor any other tool any of us know of) will give you an exact
estimation. I believe it was this thread:

Regards,
Felix
