[Libwebsockets] lws_write speed

[Pierre Laplante]

In the example of the server, you are using malloc to copy the data before using lws_write as in:

...

out = (char )malloc(sizeof(char)(LWS_SEND_BUFFER_PRE_PADDING + len + LWS_SEND_BUFFER_POST_PADDING));
memcpy (out + LWS_SEND_BUFFER_PRE_PADDING, str, len );
n = lws_write(wsi_in, out + LWS_SEND_BUFFER_PRE_PADDING, len, LWS_WRITE_TEXT);
If the buffer is very large, this copy all the data for almost nothing here.

because of that, libwebsocket is very slow. In fact an ajax based solution is twice as fast as websocket.

Is there another way to do this ?
