In chromium-gtk mode, when the big string was transported from web page to plug-in through invoke function, the elapsed time is too long. I found the root cause was that the time of WriteUtf8 operation was too expensive, when the data type of String was ConsString.

Pseudo-code in JavaScript side:
var str="";
var num=1024*1024;
for(var i=0; i<num; i++)
    str+="A";
plugin_object.writeString(str);

Suppose that plugin_object is a plugin object, and has the function "writeString" in plug-in, although the this function could do nothing.
