First of all, the check to see if the accept queue is full is implemented in an inline function called sk_acceptq_is_full in include/net/sock.h. It uses the following condition:<br /><br />sk->sk_ack_backlog > sk->sk_max_ack_backlog<br /><br />Since the comparison operator used here is ">" and not ">=", the effective size of the accept queue is actually backlog+1. This explains why you see up to 2 connections in state ESTABLISHED on the server side (one that the code in TestAccept1 accepted and one that is still in the accept queue).<br /><br />The fact that the size of the accept queue is backlog+1 and not backlog may be a bug, but don't forget that anyway the size of the accept queue can never be 0. The reason is that a connection must go through the accept queue before it can be accepted by the application.<br /><br />You also mention that "It seems like the OS also allows more than two connections to be opened, even when the backlog is specified as 0". That is actually true for Linux, but the connection will only appear as ESTABLISHED to the client. The server side socket will remain in state SYN_RCVD. The reason for this is explained in the following blog post:<br /><br />http://veithen.blogspot.be/2014/01/how-tcp-backlog-works-in-linux.html<br /><br />You can see the trace shown in my post is almost identical to the one in your third screenshot.<br /><br />PS: Note that this doesn't explain your observations about Tomcat.Andreas Veithenhttps://www.blogger.com/profile/06603931854375713558noreply@blogger.comtag:blogger.com,1999:blog-4314823943675891475.post-6139516759454203252013-11-08T01:44:30.619-08:002013-11-08T01:44:30.619-08:00Asanka,

But there is no need for that. What I have mentioned here is that there 10k messages with 4,598 and 4,361. For any system there is no reason to show low performance numbers with low payload. At least it should be same. <br /><br />As I mentioned this is not a problem of UltraESB or any other ESB (you can see the same thing with WSO2 ESB as well) but lack of messages to run the performance test. Therefore as you also has mentioned better to increase the number of messages to avoid these.<br /><br />Amila Suriarachchihttps://www.blogger.com/profile/15162735185293537609noreply@blogger.comtag:blogger.com,1999:blog-4314823943675891475.post-59940912885888615562013-10-27T04:32:22.713-07:002013-10-27T04:32:22.713-07:00Hi Amila
Thanks for your comment.. and good to he...Hi Amila<br /><br />Thanks for your comment.. and good to hear from you. Let me address the points in brief. <br /><br />a)3,895 was for the 640 concurrency with 500 bytes payload, the corresponding value for 10K at 640 concurrency is 3,554. So I am not sure exactly what you point out in this one, but in general the UltraESB has a zero-copy overhead for small payloads, but it starts to pay off significantly as the payload size increases. b) true, I agree. We used these test cases from many years back - esp when some of the other ESB failed to complete the test or took a very very long time. That's why the number of iterations were done this way - its historical. This is the reason why we would update the benchmark to be better, and your suggestions are definitely considered. c) these values are between three different runs, and yes, there is a variance, and I guess the low number of messages used (if I remember - 10) is the culprit. <br /><br />You are correct in your analysis that the number of messages should be increased, the reason why we ran this exact same test was to wrap up this benchmark one final time before starting the new one, and also to highlight some of the flaws which would otherwise be thought as facts from the 6.5 article. Again, on the analysis, we used the same style of analysis - just to be the same as our last round. We will improve on these aspects in the new benchmark.<br /><br />As someone I know who has really run valid performance benchmarks, I would be happy to work with you in future to define the new benchmark. Check the contributions to the bitbucket project so far, and you will realize that many others also would help in this endeavor.<br /><br />regards<br />asankhaAsankhahttps://www.blogger.com/profile/05768379677233692797noreply@blogger.comtag:blogger.com,1999:blog-4314823943675891475.post-60893770538436392782013-10-25T06:53:16.913-07:002013-10-25T06:53:16.913-07:00First of all I should appreciate your effort to ru...First of all I should appreciate your effort to run these performance bench marks which in fact lead to performance enhancement in esbs. But I would like to point out some inconsistence of the result obtained as I see. What are your explanations about following cases?<br /><br />a) if we take UltraESB, it has shown 3,895 for a 500b case while there are over 4000 cases for 10k. How a 10k shows a better performance than 500b? b) if we look at the average TPS values for a one message size (say 1k,10k) I can see a TPS variation with concurrency. But this is not possible. Once the system gets to a saturated sate it should shows same TPS irrespective of concurrency. c) Lets take the lk 2560 case. There the maximum TPS is 7,327 while average is 5,475. This means average for low TPS values is 4,549. That is at least 61% different between best case and worst case.<br /><br />My explanation of all these cases are not having enough number of messages to run at each scenario. Typically each scenario would have run at least 4-5 minits. I have done lot of performance tests including tests given in this benchmark and never see those problems when we have higher number of messages.<br /><br />Another thing is the analyzing part. How fair it is to take an average through all message sizes and show one performance figure? In this case the esbs perform better in higher messages sizes have a disadvantage. Again good example is UltraESB. It has show better result in 100k messages but has not reflected that in final results. In this case we need to draw graph for each and every case and show how performance varied with the messages size. This way readers can get a much better idea about the behavior of the esb according to their scenarios and pick the best.<br /><br />You have indicated you are going to change the benchmark for next testings. So what I would like to suggest is to fix those as well. <br />Amila Suriarachchihttps://www.blogger.com/profile/15162735185293537609noreply@blogger.comtag:blogger.com,1999:blog-4314823943675891475.post-73083784088711550772012-11-01T00:29:55.428-07:002012-11-01T00:29:55.428-07:00Nice and clear article!Nice and clear article!Peterhttps://www.blogger.com/profile/10090345212414207510noreply@blogger.comtag:blogger.com,1999:blog-4314823943675891475.post-47456147906486512052011-09-05T03:50:14.246-07:002011-09-05T03:50:14.246-07:00I'd like to see Open ESB in there...I'd like to see Open ESB in there...Paucus3dhttps://www.blogger.com/profile/14572588007365607557noreply@blogger.comtag:blogger.com,1999:blog-4314823943675891475.post-14815481720885091482011-08-12T06:13:33.043-07:002011-08-12T06:13:33.043-07:00Federica, thanks for the option, I had not heard a...Federica, thanks for the option, I had not heard about it before..<br /><br />The Wiki being in Italian is not that good, especially since I was looking for some easy examples (e.g. a SOAP proxy service) to get started..
