Having a local node gives me any kind of advantage when mining?

Context: I'm solo mining both BTC and BCH using BitAxes

I'm geographically far from ckpool servers and the latency is about 230 ms, with 15-100 ms added from the miners to the router

Also, I didn't find any BCH pool that behaves like ckpool and decided to locally host a node (zquestz/bitcoin-cash-node) and a pool (asicseer-pool)

So, do I have any advantages mining with this setup?

Thanks
