Hi Frederic<div><br></div><div>I thought that might be the problem too :). But this happens in different vms and operating systems. My dev pc (where it works perfectly very high throughput and low very low latency) is a mac on sun java 1.6(64bit). My small test setup @home (where the problem also happens) is my mac + a ubuntu running sun java 1.6 (32bit) too. In the cluster I have multiple configs, some of the machines are pentiumD 3.0 (1) and some are core2duo (2) they all run centOs. All the 1's are running sun java 32bit and at first all the 2's were running iceTea jdk 7, 64 bit. Having 1 as server 1 as client, the throughputs are not that great but in singe thread the latency is stable (not in multithread). Running 1 as server 2 as client the latency becomes unstable. I tryed changing the vm from iceTea to sun java but it still happens.</div>
<div>As you can see I think the diverse environments rule out the specific jdk reason, but I could be wrong. Any ideas?</div><div><br></div><div>Regards</div><div>David</div><div> </div><div><br><div class="gmail_quote">On Wed, Feb 25, 2009 at 8:39 AM, Frederic Bregier <span dir="ltr"><<a href="mailto:fredbregier@free.fr">fredbregier@free.fr</a>></span> wrote:<br>

Hi David,<br>
<br>
Just a quick question : what kind of servers do you use?<br>
(OS and level, JDK editor, level and 32 or 64bits)<br>
It may be not related, but I observed already some problem on a buggy JDK<br>
but not with the same behaviour as yours.<br>
