What's the difference between Standard, Turbo and Godly Modes?

These are speed of transaction mirroring settings. Turbo is best bang for buck. Godly is about 10x more than that.

FEES

Standard: ~0.002 SOL (Very Fast)

Turbo: ~0.006 SOL (Even Faster)

Godly: ~0.06 SOL (Usually Overkill, only use if you REALLY know what you're doing)

Go ahead and test. Our transactions land on chain faster than the copied transactions are even confirmed.
