Normally, small requests performance depends on proxy CPU, but disk model matters, especially for writes. If no bottlenecks on keystone, and disks aren't too bad, I assume over 1000 op/s can archive with one proxy plus 5 storage modes with your pattern.<br><br>-ywang</div><div><br>在 2012-10-25，1:56，Alejandro Comisario <<a href="mailto:alejandro.comisario@mercadolibre.com">alejandro.comisario@mercadolibre.com</a>> 写道：<br><br></div><div></div><blockquote type="cite"><div><div><font color="#000000"><font><font face="courier new,monospace">Guys ??</font></font></font></div><font color="#000000"><font><font face="courier new,monospace">Anyone ??</font></font></font><div><font color="#000000"><font><font face="courier new,monospace"><br clear="all">

<p>While I can't answer your question (I've never used swift) - it's worth mentioning many of the openstack folks are en-route/at the design summit.</p>
<p>Also - you might have more luck on the openstack-operators list, rather than the general list.</p>

<div>Regarding the networking, each proxy / datanodes has a dual 1Gb nic, bonded in LACP mode 4, each of the proxies are behind an F5 BigIP Load Balancer ( so, no worries over there ).</div><div><br></div><div>Today, we are receiving 5000 RPM ( Requests per Minute ) with 660 RPM per Proxies, i know its low, but now ... with a new product migration, soon ( really soon ) we are expecting to receive about a total of 90.000 RPM average ( 1500 req / s ) with weekly peaks of 200.000 RPM ( 3500 req / s ) to the swift api, witch will be 90% public gets ( no keystone auth ) and 10% authorized PUTS (keystone in the middle, worth to know that we have a 10 keystone vms pool, connected to a 5 nodes galera mysql cluster, so no worries there either ) </div>
<div><br></div><div>So, 3500 req/s divided by 6 proxy nodes doesnt sounds too much, but well, its a number that we cant ignore.</div><div>What do you think about this numbers? does this 6 proxies sounds good, or we should double or triple the proxies ? Does anyone has this size of requests and can share their configs ?</div>
<div><br></div><div>Thanks a lot, hoping to ear from you guys !</div><div><br></div>-----<br>
