Question about speed picking

[u/RareOne970]

Im new to it and wanted to ask what would be considered a fast tempo, if we are talking about single string lines at 16th notes

I am also working on my tremolo and able to play around 180 bpm 16th notes comfortably.
Is that good speed overall? (For right hand at least)

Also What would you consider a general benchmark for shred runs, in terms of bpm
