Jimmy Lai <yuri...@gmail.com> added the comment: @vstinner In general, we would like to make all asyncio common functions efficient with C implementation because CPython asyncio overhead is very expensive. In our application, overall it costs about 10% global CPU instructions after we used UVLoop (it's much worse when use default event loop). gather() is only one of the high level function bottleneck. To make CPU overhead not a concern for asyncio user, we should make isfuture in C because it's called by many other event loop functions, e.g. in asyncio/tasks.py, asyncio/coroutines.py, asyncio/base_events.py
