Hi Artem,<br>
<br>
I was wondering if the 4th replica is adding additional overhead (another dir to check), but the test is not very conclusive.<br>
<br>
<br>
Actually the 'anomalities' log entries in your pool could be a symptom of another pdoblem (just like the long listing time).<br>
<br>
I will try to reproduce your setup (smaller scale - 1 brick 50k files) and then will try with 3 bricks.<br>
<br>
<br>
Best Regards,<br>
Strahil Nikolov<br>
