This grid was composed of 36 geographically dispersed nodes exclusively to send the txs, that was sent by each one randomically. All interconnected with each other and externally.
We want to have dedicated connection to external nodes also, I will contact you in priv to get the information to connect to your node, this will be very good. Thank you very much!
I have configured my node to maximize connections and set up memory according. I can hold 4GB worth of unconfirmed TX before raising relay fee, and have 8gb for cache out of 32gb.
