CLI: parsing large files takes significant time to print result

      When running the performance subcommand of the CLI to parse a 10MB file, the parse completes in under 10 seconds. When using the parse subcommand, it takes over 10 minutes to get the result.

      I ran the parse in verbose mode, and I get the following output:
      [info] Time (compiling): 1773ms
      [info] Time (parsing): 10542ms
      [info] Time (writing): 652815ms
      that's about 2 seconds for the compilation
      10 seconds for the parse
      and about 10 minutes to print the output
