Hi Douglas,<br><br>Thank you so much for this work. We are trying to come up the learning curve on the XS and scalability and I'm sure that I care about this data.<br>Deds and I have been contemplating these and your previous results this morning and moving ourselves up the learning curve.<br>
<br>TLS = ttp://<a href="http://en.wikipedia.org/wiki/Transport_Layer_Security" target="_blank">en.wikipedia.org/wiki/Transport_Layer_Security</a> correct?<br><br>When you test old and new TLS there are code changes on both XO and XS?<br>
<br>What releases are the control setup? IS the New TLS released code?<br>
<br>Questions about the methodology.<br><br><ul><li>1 connection models 1 user?</li><li>Does it just connect? does it share any activities? would sharing activities affect the outcome in XS in any way?<br></li><li>Have you tested with current shared roaster vs a roster grouping system that only allows say 30 or 50 people in any online users roaster at once? If not do you expect that to be an important factor?</li>
</ul>Thanks,<br>Caroline & Deds<br><br><br><br><div class="gmail_quote">On Fri, Nov 21, 2008 at 5:34 AM, Douglas Bagnall <span dir="ltr"><<a href="mailto:douglas@paradise.net.nz" target="_blank">douglas@paradise.net.nz</a>></span> wrote:<br>

memory and CPU consumption with the new tls code, as shown here:<br>

This is based on these two test runs:<br>

<br>
which can be found in raw form, and converted into graphs via the<br>
next two links:<br>

<br>
These are different tests than the one I reported a few weeks ago,<br>
which was conducted without the shared roster. Evgeniy asked if I<br>
could repeat that test with SMP disabled, but it happens that I can't<br>
because I've lost one of the computers that ran the clients. I could<br>
re-run this one without SMP if that was likely to be interesting.<br>
<br>
It looks like the cost of @online@ shared roster outweighs the cost of<br>
TLS. That's about as insightful as I get at this time of night.<br>
