hello everyone, we're doing some load testing with pushpin, and we found a weird behavior. Our set up is like this:
websocket client <= pushpin <= backend <= redis. We create 200 redis pub/sub topics and 200 websocket clients (1 per topic) and hammer redis. Our backend server is subscribed to all the topics and relay the messages back to pushpin by making POST calls. The weird behavior is that most of the POST calls made by our backend server to pushpin only take about 2 milliseconds, but occasionally they take more than 300 ms. Any idea why this might be happening?
