c/c++ auto-complete performance

[ahkevin]

I noticed that SE lag when I work on a large c/c++ project( > 10K files).
I searched the forums and found a topic had discussed the issue.

When will this feature be implemented? Will it be in V27?

A large portion of the auto-complete core engine code was re-written in C++ for version 26.  The language-specific code still needs to be rewritten, and nothing is thread-safe yet (really can not make much thread-safe until the language-specific code is thread-safe).  I do not know if this will be completed for v27 or not.

Frequently performance issues with C++ trace back to preprocessing making code parse incorrectly and gums up the gears.  Sometimes it's just too many layers of type-inference and template expansion.  Really have to investigate and come up with reproducible cases for specific issues that come up laggy.

It is same issue in large C project, such as linux kernel.

Are you seeing it as an everywhere issue, or in certain cases?

One thing you could do since you have a larger project, is to dial down some of the Auto-Complete sub-word matching options to be less aggressive.

It is an everywhere issue in my opinion.
Yes,You're right. It does ease the issue, but it's not complete, sometimes there are still laggy.
