Description jcreyf 2014-01-03 06:02:32 UTC

[ BUILD # : 201401020002 ]
[ JDK VERSION : 1.7.0_25 ]

I've been concentrating on JavaScript development and am getting quite a few
silent "slow code completion detection" warnings.
It can take up to 7 seconds for a completion to finish.
I'm not seeing these delays in Netbeans 7.4, so I assume this is related to new
development.

Please attach some profiling snapshots (see [1]) during the slow autocompletion. Thank you in advance

Profiler output for another slow code completion

I had installed a fresh Netbeans daily build (201401060002) and apparently forgot to configure the proxy server for the first profiler snapshot.  Not sure if that makes a difference, but I decided to fix the proxy settings, bounce the IDE and try again.
This profiler output is for a new slowness warning without network connectivity issues.

Hi Vladimir,

I've updated to daily build 201401060002.
This build seems better with fewer slowness reports.
I captured occurrences in the profiler and attached both the profiler output and IDE logs.

I work in 2 different locations.  One where I need to go through a proxy server to get onto the internet and another where I have direct access.
I had forgotten to flip the proxy server settings in the IDE when I captured the first issue, so I decided to fix the setting and bounce the IDE.  Then I captured the 2nd slowness occurrence and attached the files for that too.

As I said, I seem to be getting fewer warnings in this build.
I'll use it for a couple days and will update the ticket if the situation changes.

Thanks,
Jo
