Selecting multiple lines slows down pretty hard

[WhyNotHugo]

When entering visual mode, as I select more lines nvim slows down a lot. With 10-20 lines there's almost a second of lag, but with ~100 lines selected, nvim grinds to a halt taking several seconds to respond to any movement.

My impression is that the problem is because each line is fetched from git individually, and this just piles up hundreds of calls to git.

I'm no expert here, but I do think that some of these approaches might help:

• Cache git blame while the file does not change.
• Get all blame data for the entire file at once and parse that internally.
• Auto-disable when selecting more than n lines (n can be either hardcoded or configurable?).

Same problem here!

I turned blamer off for visual mode. I don't really need it in visual mode anyway, and it gets rid of the slowness:

-- In visual mode it's visually annoying AND slows down Vim A LOT.
vim.g.blamer_show_in_visual_modes = 0

I think 'Auto-disable when selecting more than n lines (n can be either hardcoded or configurable?).' would be really helpful.

That's pretty much what blamer_show_in_visual_modes does, but for n==1.
