The tools/performance directory contains several scripts that may be used to evaluate the performance level the E-Maj extension on various points of views. 

More precisely, it contains the following directories:

- tools/performance/dump_changes, to measure the changes dump operations performance with each consolidation level;
- tools/performance/large_group, to measure the elapse time of main E-Maj functions with large table groups (ie. containing a big number of tables);
- tools/performance/log_overhead, to evaluate the overhead of the logging mechanism, using pgbench;
- tools/performance/rollback, to appreciate the rollback operations performance with various types of data updates.

Each sub-directory contains a single shell script that needs to be customized.
