I may have missed it but where under the repo (https://github.com/minborg/javapot) are the MyUnit3Terminal and Unit3Terminal classes?

Hi Óscar and thank you for your question!

The test should work because it sets up the same "seed" for the Random generator each time.

Happy coding!

The seventh test of Unit 1, infiniteRandomInts(), is suppossed to pass?
Each ejecution will generate different values, isnt it?

Anyway, thanks for the article!

Hi. Not sure I understand your comment. I am using JMH and I do return the result of the computation to avoid dead code elimination. So, I believe the results are accurate and representative for the different variants.

In your example, you use blackhole to consume the result which is another way of eliminating dead code elimination.

Wouldn't it be better to avoid compiler optimi...

2019-09-12T08:09:46.374-07:00

Wouldn't it be better to avoid compiler optimisations to get more accurate results and use the techniques here (http://tutorials.jenkov.com/java-performance/jmh.html) ?
This is how I used it in practice https://github.com/pgilad/java-micro-benchmark-example/blob/master/src/main/java/org/sample/ArraySlicingBenchmark.java

Thanks for the link that looks very interesting. I am aware that the "10k" varies depending on a number of reasons. This could be a topic in a separate article. Thanks for your comment and let me know what you think about the library.

You should read this: https://shipilev.net/blog/20...

2019-08-16T18:36:08.703-07:00

You should read this: https://shipilev.net/blog/2015/black-magic-method-dispatch/. Taking "another" path is not that dramatic and ultimately is something you very rarely care about. Also that 10.000 calls is a myth that just would not die! https://stackoverflow.com/questions/53885832/why-is-server-option-there-when-server-vm-is-the-default-option/53887071#53887071 disclaimer, that is my answer. Interesting library, will look for sure! Very eager to find out how you handle parallelism and databases that support native "streaming" over it's entries.

2019-08-12T08:36:37.861-07:00

You are perfectly right. I think that the article could be much clearer in this perspective. As you have pointed out many times, there are ways to send a message across a TCP/IP network with lower latency.

2019-08-12T08:34:24.403-07:00

I only commented because you mentioned 'theoretical minimal latency'. The theoretical minimal latency can only be achieved when you modify all things available (in this case the kernel and all software-layers involved).

I admire your persistency. Let me explain why thes...

I admire your persistency. Let me explain why these references are not relevant to the article:
https://www.openonload.org/ Bypasses the kernel. The article specifically includes the kernel
http://www.coralblocks.com/index.php/coralreactor-performance-numbers/ Tests were made using the loop back interface on the same physical machine.
https://wiki.fd.io/images/f/f4/02_ld_Light_A_scalable_High_Performance_and_Fully_compatible_TCP_Stack.pdf appears to bypass the kernel but it is just a slideshow so hard to tell.
https://eggert.org/papers/atc16-paper_yasukata.pdf "StackMap leverages the best aspects of **kernel-bypass**
networking into a.." Again this is by bypassing the kernel.

Another aspect is that my tests were run on an old MacBook pro. It is likely that the latencies for the Streams would be even lower on modern hardware and the latest version of C2 compilers. So, in fact, the ratio could be even higher than proposed in the article.

I am interested to learn if you have a reference with sub 15 us latencies for the given requirements. Keep looking!
