Yes, you can see quite a lot of * compared to +, but that doesn't mean much, since we don't know how big is your difficulty and with what difficulty dstm dev mining, since it is mining on Flypool and he could adjust that to some lower difficulty.

The best way to check is to compare your Sol/s in dstm over what your pool is showing when you leave it running for 24h.

In my case it was DSTM miner 345 Sol/s, Flypool arround 337 Sol/s, on GTX 1060 6GB.
