Incredible slow since DSM 7.1

[Tobias2k]

Hi folks,

I've upgraded my Terramaster F4-220 (J1800 Dual-Core Soc, 4GB Ram) from DSM 6.2 to 7.1 last weekend, which worked out so far.

Unfortunately the system gets incredible slow as soon as you start a simple task. For example I just activated one camera in surveillance station and the whole system is unreachable since 10 minutes. I recognized this behavior right after installation. I thought the system needs some time to index the files so I gave the nas a day to work. The tasks seemed to be completed because the CPU load was only a few percent this morning. But the behavior with activating one camera tells me that something isn't right with the DSM. Under DSM 6 I had 3 cameras, jdownloader and a docker virtual machine running without any issues.
