When a load test is run on my service, after about 1000-1500 requests, I get this stack trace. I am unable to resolve why it was generated. Yes, the output from the service is passed to an output channel and is read through that channel. I am doing something like this: package main import (

Update, after running this program several times the 112mb/sec number is limited by how quickly the file could be streamed off disk. Once the source file was cached, the time to upload 7.4 gb dropped to around 3 seconds, so ~ 2.5 gb / sec, which is more reasonable for the loopback. What do you

Hi Kai, I had a quick play with this simple server https://play.golang.org/p/LFx0HmXK4q This simple server took 67 seconds to upload a 7.4gb file over the loopback interface, which is around 112 mb per second, which is faster than what you are seeing, but not that fast either, given it's on th
