Virtual memory will not affect device device performance too much.
If the physical memory is exhausted will effect the system, kernel,
As long as the system is running normally, it can be ignored.
The problem is, that daily or nearly daily at some point, latency spikes up, pinging the router or the host router will go from 1-3ms to 200ms, as well as dns query speed and loading any website becomes extremely slow if it loads at all, ping to sites becomes 800ms+ or so at this point, and ping between wireless or wired devices on network will jump around 1-200ms, requiring a reboot.
Why is dnscrypt trying to reserve 250% of available memory though
