The files in this subdirectory are used to help measure the performance of the SQLite JSON parser.

1.0 Prerequisites

  1. Valgrind

  2. Fossil

2.0 Setup

  1. Run: "tclsh json-generator.tcl | sqlite3 json100mb.db" to create the 100 megabyte test database. Do this so that the "json100mb.db" file lands in the directory from which you will run tests, not in the test/json subdirectory of the source tree.

  2. Build the baseline sqlite3.c file. ("make sqlite3.c")

  3. Run "sh json-speed-check-1.sh trunk". This creates the baseline profile in "jout-trunk.txt".

3.0 Testing

  1. Build the sqlite3.c to be tested.

  2. Run "sh json-speed-check-1.sh x1". The profile output will appear in jout-x1.txt. Substitute any label you want in place of "x1".
