[英]TCP receiving and sending buffersizes in node.js
I have been working with node.js for the last 4 month and now wants to increase tcp receving and sending buffersize. 我在过去4个月中一直在使用node.js,现在想增加tcp接收和发送buffersize。
My purpose is to speed up my application and expermantation with buffersizes may increase preformance. 我的目的是加快我的应用程序的速度,使用缓冲区大小的实验可能会提高性能。
I have searched on google but haven't found anything useful except that you can change the default socket buffersizes on linux as example on this website: 我已经在Google上进行了搜索,但没有发现任何有用的信息,除了可以在以下网站上更改Linux上的默认套接字缓冲区大小:

Is there any way to change/set tcp sending and receiving buffersizes for node.js io? 有什么方法可以更改/设置node.js io的tcp发送和接收缓冲区大小吗?
stream_wrap has an allocation callback passed to libuv that is passed a suggested_size of the allocated memory to use in the receiving the data. stream_wrap具有传递给libuv的分配回调,该回调已传递给已分配内存的Recommendation_size,以用于接收数据。 Right now it passes 64KB as the suggested size, and there's no way to change this afaik. 目前,它以建议的大小传递64KB,无法更改此afaik。
Is this along the line of your question? 这是否符合您的问题?
I found the stream_wrap on git: 我在git上找到了stream_wrap:
git... src/stream_wrap src file git ... src / stream_wrap src文件
And if you navigate src/stream_wrap.cc in node.js src folder and looking up following code: 而且,如果您在node.js src文件夹中导航src / stream_wrap.cc并查找以下代码:
// If less than 64kb is remaining on the slab allocate a new one.
if (SLAB_SIZE - slab_used < 64 * 1024) {
slab = NewSlab(global, wrap->object_);
} else {
wrap->object_->SetHiddenValue(slab_sym, slab_obj);
}
}
Then you might be able to change the size. 然后,您可以更改大小。
