Re: help with my inefficient instaparse grammar
Use :optimize :memory maybe? Section 10 here seems like your use
case: https://github.com/Engelberg/instaparse/blob/master/docs/Performance.md
Watch htop and see if you have a process that is hitting swap without the
optimization.

The above grammar simply parses a map in lua-syntax. It works for the
above case. However, when I try to use it on a file that is about 1 MB in
size, it fails(not sure didn't wait longer than 2 minutes). I would love
to hear if there is something that is grossly inefficient in the way I have
represented my grammar. The lua interpreter loads the file in no time (well
0.06 sec) . I would love any feedback on improving the grammar. Thanks
