I am doing Electron development. I got a performance problems. In my project, I used libuv to do async request and callbacks. The event loop is uv_default_loop(). Two kinds of handles are created, one for common callbacks and the other is for http request.
What I observe is that the http request is invoked after a large latency - (around 100ms) while the common callbacks are invoked almost immediately.(1ms). Could anyone tell me what is the possible cause？ How can I check where is the bottleneck? Is there any solution to shorten the latency? Thanks!
