Heikki Linnakangas 49c8c03465 Add performance test for bulk INSERT 2021-09-21 13:25:46 +03:00
Heikki Linnakangas c6678c5dea Include # of bytes written in pgbench benchmark result 
Now that the page server collects this metric (since commit 212920e47e),
let's include it in the performance test results

The new metric looks like this:

    performance/test_perf_pgbench.py .         [100%]
    --------------- Benchmark results ----------------
    test_pgbench.init: 6.784 s
    test_pgbench.pageserver_writes: 466 MB    <---- THIS IS NEW
    test_pgbench.5000_xacts: 8.196 s
    test_pgbench.size: 163 MB

    =============== 1 passed in 21.00s ===============

Heikki Linnakangas 074bd3bb12 Add basic performance test framework. 
This provides a pytest fixture to record metrics from pytest tests. The
The recorded metrics are printed out at the end of the tests.

As a starter, this includes on small test, using pgbench. It prints out
three metrics: the initialization time, runtime of 5000 xacts, and the
repository size after the tests.
