Maybe not. This bug report: 
https://github.com/abingham/emacs-ycmd/issues/163 mentioned large 
translation units, but I'm not sure which exact sizes are in play. The 
reproduction scenario used a 300 KB example, encoding which was quite 
slow at the time.

If you mean I/O in general, maybe. I'm not sure which encoding speeds 
json.c allows us now.

But the JSON structure I was talking about is not written to a file. 
It's sent over the network (usually to a local TCP socket).
