How to Reduce Transaction Execution Time on Sui Chain?

[qxyanda]

I am currently executing

executor.executeTransaction(tx)

, and it typically takes over 1 second for the transaction to be recorded on the Sui chain.

Since we are developing a game that requires strong real-time performance, is there any way to significantly reduce this time? For example, can we shorten it to around 100ms?

Can deploying a full node significantly reduce latency? If I use my own full node, how can I correctly send transactions? As far as I know, full nodes do not have the ability to validate transactions.

Or, How can I find the lowest latency full nodes/validators near me?

Thank you!
