Bug ID: 369374
Summary: Background parser slows down the GUI thread for large
projects
Product: kdevelop
Version: 5.0.1
Platform: Debian unstable
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Language Support: CPP (Clang-based)
Assignee: kdevelop-bugs-n...@kde.org
Reporter: legnale...@gmail.com
I'm working on Gecko, and I found since Kdevelop 5.0, the background will make
GUI very heavy.
The CPU utilization of GUI thread is very high (~100%), but other threads are
nearly zero.
When I attach it to gdb, I saw many thing like this:
[New Thread 0x7f96867fc700 (LWP 16248)]
[Thread 0x7f96867fc700 (LWP 16248) exited]
Looks like it keeps create lots of short-living threads?
Reproducible: Always
Steps to Reproduce:
1. hg clone https://hg.mozilla.org/mozilla-central
2. use kdevelop 5.0.1 to open it
