+## Some performance results
+
+We present the time (in cycles per input byte) needed to fully parse a JSON file (with error checking) and to collect some statistics about the document (e.g., the number of integers), for some JSON files. For these tests, we use an Intel processor with a Skylake microarchitecture. All results are single-threaded.

 - `json2json -d mydoc.json` parses the document, constructs a model and then dumps model (as a tape) to standard output. The tape format is described in the accompanying file `tape.md`.
-- `minify mydoc.json` minifies the JSON document, outputting the result to standard output. Minifying means to remove the unneeded white space charaters.
