Hi there, I've been experiencing latency while having the WhatPulse app open since I started to play some games on my Mac. I didn't realise right away that the WhatPulse app was causing this issue, but it seems that it does.
The problem is that around every 10 seconds, my latency dramatically increases for 2-3 seconds. My normal latency sits around 5-20 ms, whereas the peaks I'm experiencing can go up to 100-1000 ms.
I tested this by pinging google.com from the terminal, see the following results where the WhatPulse app is open:

The ping intervals are around 1 ping every second.
The latency on the data i just listed is actually still fairly low, I would sometimes even get latency from 300ms-1000ms. I've run several tests in the past week and I'm confident that the WhatPulse app is causing the latency spikes.
Is there any reason why my latency shoots up every ~10 seconds?
I am running macOS Sierra 10.12.2 on a 15-inch MacBook Pro Late 2016.
I am using WhatPulse client 2.7.1 (which is currently the latest).
