Many things, including a log timing report in the test

Browse Source 
Timing report:

I (52322) LOG_TEST: === WRITE TIMING REPORT ===
I (52322) LOG_TEST:   Iterations:       200
I (52322) LOG_TEST:   Payload size:     39 bytes
I (52322) LOG_TEST:   Min:              49960 us
I (52332) LOG_TEST:   Max:              54476 us
I (52332) LOG_TEST:   Avg:              50005 us
I (52342) LOG_TEST:   Sector crossings: 2 (max 49983 us)
I (52342) LOG_TEST:   WDT margin:       4.9s (WDT=5s, worst=54476us)
I (52352) LOG_TEST: ===========================

so a write takes up to 54ms - not negligible!
