Load testing #147

Open tbglazer opened 2 years ago

We use mq-mqi-nodejs 0.9.17 in a ms that receives HTTP requests from clients puts them on a queue and waits for response on another queue using the request message id. Sending single requests works well, but when load testing by sending several requests at a time the MQ GET gets stuck after a random number of requests (even that a timeout is specified in the get request) and freezes the application. Moreover, in one case it returned the wrong data belonging to another request. My question is: did you ever performed tests of the package in a scenario that I described ? To solve temporarily we did a very nasty workaround by putting the GET inside a section locked with a mutex but this makes all requests to be executed sequentially which is not how it should work.

I have done some stress testing, though it's not likely to be an exact match for yours. There was a fix put into v0.9.23 that affected some of the async retrieval. Tt doesn't immediately sound like the same thing, but it might help.
