Separate very slow pygments colorizing from JSON indentation

[acdha]

The Pygments JSON colorization is nice but noticeably slow. I would love to have separate --indent and --colorize options rather than simply --ugly which would be equivalent to http URL | python -m json.tool, which appears to be 3-4 times faster in my testing.

Approximately how large are the responses where the delay is noticeable?

I've tried to compare the following a couple of times:

time http GET https://api.github.com/repos/jkbr/httpie/watchers

Vs.:

time http --ugly GET https://api.github.com/repos/jkbr/httpie/watchers

And haven't noticed any difference.

It would be great if you could post some numbers on the rendering speed vs. response size with the relevant URLs (if possible).

They are somewhat large - currently around 224KB uncompressed:
