Created attachment 147573 [details]
Profiler recording of just typing some code in brand new cpp file.

I have a CnD project on Linux, and the cursor sometimes falls seconds behind while typing. In general, typing is very choppy and extremely frustrating.

NetBeans is running on a 32-core machine with 16 GB of RAM, and SSD disk space. It has been given nice=-20 and ionice=realtime, so it has the highest CPU and IO priority on the system. It's running with -Xmx4120 and -XX:+UseConcMarkSweepGC.

I'm hoping something in the attached profiling snapshot stands out. If you have any suggestions on what to do to improve the responsiveness, they'd be most welcome.

Hi stiffuser,

Could you check development build:
http://bits.netbeans.org/download/trunk/nightly/latest/
Does issue still exist?
