Interactive Blame doesn't appear to be as fast as tig or non-interactive git blame

Hi, I came to check out this project because I'm looking for a tool for command line interactive blame. I do a lot of source code archaeology , and I would like a single key-press way to go back to the commit that introduced the line in my cursor. As an LLVM developer, I was super excited to try out a project advertised as "blazing fast Rust". :)

However, I ran gitui blame on [llvm-project/llvm/lib/Target/X86/X86ISelLowering.cpp,](https://github.com/llvm/llvm-project/blob/main/llvm/lib/Target/X86/X86ISelLowering.cpp) (helpfully github says "(Sorry about that, but we can’t show files that are this big right now.)") and it's still going as I type out this issue / feature request. This isn't a bug so much as, if you are interested in doing further performance engineering and looking for a workload to benchmark, profile, and optimize, I think you should consider this one.

This source file may be a crime against software engineering, but I will say I've done my part to move code out of it, although it was almost entirely done in self-interest.
