The v2.5.0 for gnet
is officially released!
The two major updates in this release are feat: support edge-triggered I/O and feat: support multiple network addresses binding.
Intro
In #576, gnet
implemented edge-triggered I/O on the basis of EPOLLET
in epoll
and EV_CLEAR
in kqueue
. Before v2.5.0, gnet
had been using level-triggered I/O under the hood, now developers are able to switch to edge-triggered I/O via the functional option: EdgeTriggeredIO
when developing and deploying gnet
services. In certain specific scenarios, edge-triggered I/O may outperform level-triggered I/O, as a result of which, switching gnet
from LT mode to ET mode can lead to significant performance improvements. But note that this performance boost is only a theoretical inference and may only occur under specific circumstances. Therefore, please use ET mode with caution and conduct benchmark tests to collect sufficient numbers before the deployment in production.
Another useful new feature is #578, with which developers are allowed to bind multiple addresses(IP:Port) in one gnet
instance. This feature makes it possible to build and run a gnet
server that serves various protocols or a specific set of backend services.
In addition to these two major features, we've also made a good deal of code optimizations: refactoring and streamlining the core code, as well as optimising the structure.
