Hi Radim<br><br>If you run the test with only 2 nodes and FC disabled, it's going to perform even better. But then as you increase the number of nodes, the speed with no FC will drop dramatically (when we didn't have RSVP enabled, with only 3 nodes, it didn't manage to send 1 x 10MB message in 10 minutes).<br>
<br>Please run the tests with as many nodes as possible and just 1 message x 10MB. If 500k still performs better, create a JIRA to change the default.<br><br>Cheers<br>Dan<br><br><div class="gmail_extra"><br><br><div class="gmail_quote">

Sorry I haven't specified the amount, I am a stupido... my tests are working with 500k credits.<br>
<br>
UUPerf (JGroups 3.2.4.Final-redhat-1) from one computer in perflab to another, 2 threads (default), 1000x sends 10MB message (default chunkSize = 10000 * our entry size is usually 1kB) executed 3x<br>
<br>
200k: Average of 6.02 requests / sec (60.19MB / sec), 166.13 ms /request (prot=UNICAST2)<br>
Average of 5.61 requests / sec (56.09MB / sec), 178.30 ms /request (prot=UNICAST2)<br>
Average of 5.49 requests / sec (54.94MB / sec), 182.03 ms /request (prot=UNICAST2)<br>
<br>
500k: Average of 7.93 requests / sec (79.34MB / sec), 126.04 ms /request (prot=UNICAST2)<br>
Average of 8.18 requests / sec (81.82MB / sec), 122.23 ms /request (prot=UNICAST2)<br>
Average of 8.41 requests / sec (84.09MB / sec), 118.92 ms /request (prot=UNICAST2)<br>
<br>
Can you also reproduce such results? I think that suggests that 500k behaves really better.<br>

| What value would you like to use instead?<br>
