SonarJava 6.0.1 is slower than 5.14 and this impacts our PR analysis time

our builds have started taking 3x more time… With the rules we had in place, it used to take 10mins for the analysis and now its taking ~30mins… This is really unacceptable for our PR workflow… Wondering what can we do here? Is there a timeline to look at the performance issues?


We went from 2 minutes to 8 or so, not too great either. Is there anything we can do to speed this up and/or help in debugging the performance of Sonar?

Don’t think you can do much about, better stay with SonarJava 5.14 for now.
Had the same experience, it’s even a bit more than 3x.
Already opened a support case with debug logs, see

Let’s see what the guys come up with.
I only wonder why this massive performance loss didn’t came up with the tests already !? :thinking:
This is too obvious to be overseen.

We’re seeing the exact same issue on our end - Sonar 8.1 with SonarJava 6.0.1. Went from ~25 minutes to 4 hours analysis time. Seeing the comment on the Java Analyzer changes being integrated into Sonar 8.2 here:

I’m concerned about being able to stay up to date.

Hello everyone, thanks for your inputs.

The issue you are talking about is related to MMF-1870.

We are fully aware of it and we are considering solutions to tackle it. I added this post to the ticket to keep track of it, you will be able to follow the evolution there.

In the meantime, it would be very helpful if you confirm that it is indeed Sensor JavaSquidSensor badly impacting performances, and not others sensors (JavaSecuritySensor, other language sensor, …), in order to eliminate others variable from the equation. You will find execution time in the analysis logs:

Sensor JavaSquidSensor [java] (done) | time=1234ms



there’s already an exisiting support ticket, see

The test uses the latest SonarScanner for Ant, as our legacy projects still use Ant as buildtool.

with SonarJava 5.14
[sonar:sonar] Sensor JavaSquidSensor [java] (done) | time=412283ms

with SonarJava 6.01
[sonar:sonar] Sensor JavaSquidSensor [java] (done) | time=11706070ms


Yes, it is JavaSquidSensor that is taking up the time. I do not have the old log, but the new log is showing more than 6 mins with JavaSquidSensor (and in the old situation Sonar was done after 2 minutes).

I can confirm we are back to the old performance levels with sonar-java 6.3. Thanks for fixing this.


Woo hoo!

Thanks for the follow-up @MikeN!
