Autocompletion is damn slow :(

[f0086]

Hi there!

I use this little program on my linux netbook (gentoo, intel 1.6GHz with multithreading and 2 GB RAM) and bash 4.x for completion. After rebuilding the cache, the completion is so damn slow i can`t use it :( If I press tab i have to wait several seconds to gain suggestions. I've tried to profiling the bottlenecks with ruby-prof, a single "mite"-call took me about two seconds and most of it are used for the selects and the maps (mostly regex-stuff)

That is way to much!

Thanks for this insight.

How many projects/services to you have? This bottleneck never showed up on my side, because I just have about 20 entries per month with 3 different services.

Give me some time, I'll think about a rewrite of the service calls.

I dont have a lot of projects or entries. The problem is the bootstrapping of the application. It takes more then two seconds to display the "I like your hairstyle" message if I just type "mite" in it. This slows down the auto-completion and make everything slow :(
