PowerStore - Latency after firmware upgrade

Hi, I have a PS5000-T that was in version 1.0.3 and I upgraded to 2.0.1, after the upgrade, the latency increased, it was working below 1ms and it started working between 3ms and 5ms.
MX7000 with 8 nodes MX740 and esxi 7.0 u2a.

I have a case open in support, but so far nothing was found.
