Autocompletion is damn slow :( #22
Description
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)
