Question

I’ve noticed that CtrlP is consistently quite slow right after a file loads or when pulling up a new buffer. It happens each time I get the

<incrementing numbers> (press ctrl-c to abort)

message. Here’s a screenshot of what CtrlP looks like when it’s being slow. Once it loads the prt path <mru>={ ... etc part, it works lightning-quick.

I’m using a fairly unmodified version of MacVim with Janus. I’m just curious about what’s going on there. I would assume that the numbers are the catalog of files CtrlP is indexing. Does it re-index at each window/buffer?

Answer 1

That’s the number of files indexed. The index is rebuilt every time you run :CtrlP in an “uncached” directory.

You shouldn’t do :CtrlP in your home directory as it’s sure to be very large: indexing it will take a lot of time and will, for the most part, be useless.

Read the documentation for how to set caching options: :help ctrlp-options.

let g:ctrlp_clear_cache_on_exit=0

is a good start.
