Re: [boost] [Performance of circular_buffer vs Queue][Multithreading may be broken]

Is this behavior expected or documented anywhere? What kind of speedup is to be expected against the std::queue implementation? If there is none, then what is the purpose of circular buffer?

You could read the relevant docs. I strongly doubt that this boost container is slower than anything in the STL when compared like for like.

True, could reproduce.

I do also have broken code on a multithreaded application that worked

fine before. I do pass the circular buffer as reference via functions from file scope, which in combination with the threads (initially starting elsewhere) somehow broke the code.

Do you do regular benchmarks against other implementations? I dont see linked graphs on your homepage.

I would like to see the benchmark results against std-implementations linked on the main page. If possible, also as simple comparison per thread count.

Could you give a full example /repro of what exactly you are measuring? Saying "container X is faster than Y" is not very helpful without showing what operations you are measuring and what the workload is. You e.g. could create a small github repository, or a gist, or put the your benchmark here: http://quick-bench.com/ Best Mike
