问题
I'm using the plugin clang_complete in Vim. The plugin could complete C++ STL accurately. But its completion speed is unacceptable. Is there any way to improve the clang_complete's completion speed?
update:Yesterday I found this,and now the omnicppcomplete could basically meet my need ,so I decided to continue to use omnicppcomplete.vim. Thak you for your answers!!

Well i heard, that using libclang.so instead of clang executable is much faster. However for reliable completion, you need to ignore errors, and im kinda lost in using libclang api. Its really not that easy. I dont know, which version of clang_complete are you using, but there is follow up plugin called same, that is updated until now by some guy. He tried to use libclang and pre-filled databases for speedup - and not only for completing, but also for context sensitive navigating.

It actually does have some problems, as it doesnt work correctly, when there is something in code, that clang compiler doesnt like. it could be ignored by old clang_complete, but not this version(at least, when you are using libclang, you are free to use also the old clang executable).

If you're not using Clang 3.0 (rc) or trunk, you may be using slower code. This has recently been worked on, due to inacceptable performance, so just updating Clang might give you the boost you need.
