The JIT-compiler is enabled by default on most x86 64-bit platforms that have a C++ compiler that can compile C++17. To verify that a JIT enabled emulator is running you can use erlang:system_info (emu_flavor). A compatibility adaptor for gen_tcp to use the new socket API has been implemented (gen_tcp_socket). If a socket has somehow been connected without using gen_tcp, use this option if all available ports in the Erlang emulator are in use.

As I read the documentation, there are two possible ways to handle stalling reader: 1) block OTP 22 has just been released. It has been a long process with three release candidates before the final release. We decided this year to try to get one month more testing of the major release and I think that the extra time has paid off. We’ve received many bug reports from the community about large and small bugs that our internal tests did not find. gen_tcp有false,active,once,N这些选项，active是不提供流量控制的，之前没读懂，疑惑了好久，后面仔细看了看，也许是这个意思：erlang的话每个进程都有个邮箱，消息就放在邮箱中，在active模式下会无限的从底层接收缓存中提取消息到邮箱中，邮箱满了消息就会丢失。 econnrefused on gen_tcp:connect. I am getting {error,econnrefused} on any call to gen_tcp:connect even though 1) epmd is running and epmd -names returns the correct result; 2) ping works fine.

So the idea is all the listening and accept stuff is handled successfully at the top of a gen_server.

DESCRIPTION 在erlang开发中使用erlang send是比较方便的，但是性能相比使用socket会有多大的损失呢。 测试程序： 客户端： 1.使用erlang send 发送1M次数据，每次一个整数 2.使用gen_tcp连接，发送1M次数据，每次一个整数 服务器端： 基于ranch socket框架,开发简单的socke 服务端使用erlang实现的简单echo功能，客户端采用C#开发的Winform程序。客户端开启1000个线程，每个线程向服务端发送多次固定文本，并从服务端接收返回的内容。 gen_tcp有false,active,once,N这些选项，active是不提供流量控制的，之前没读懂，疑惑了好久，后面仔细看了看，也许是这个意思：erlang的话每个进程都有个邮箱，消息就放在邮箱中，在active模式下会无限的从底层接收缓存中提取消息到邮箱中，邮箱满了消息就会丢失。 gen_tcp nonblocking send.
