Hello. I am currently running a monerod node on a VPS that's run by inux Ubuntu 16.04. It's synced, wallet's set up and connected to it as well. The CPU of the server is Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz

I have already consulted ./monerod help, which tells me to mine with command start_mining addr [threads]

But no matter what number I put on [threads], it keeps mining at 6 H/s, net hash 12.62 MH/s, v1, up to date

What am I then supposed to do to increase hash speed?!
