IntelliJ IDEA debugger is too slow on my new MacBook Pro 13 inch TouchBar model (late 2016). It has an i5 2.9ghz (6th Gen) and 8 GB ram.

Is there something wrong with processing power or is something else wrong? On my pc (i5 4670k, 8gb) the same version runs fine.

You may have a problem with DNS, see the following answer:

git clone https://github.com/thoeni/inetTester
java -jar ./bin/inetTester.jar

Find the hostname that's output from the .jar.

sudo nano /etc/hosts and add these two entries.

127.0.0.1 <output-host-name>.local
::1 <output-host-name>.local

Agree with CrazyCoder. There is an easier way for obtaining/modifying hostname instead of using the github repo.

  1. In system preference, click sharing

2. Click edit in the popup window. In my case, the hostname is MacBook.local.

3. sudo vi /etc/hosts

IntelliJ 2020.1 User interface very laggy/slow response compared to , IDEs Support (IntelliJ Platform) | JetBrains Java: slow performance or hangups when starting debugger and stepping Follow Method breakpoints will slow down debugger a lot because of the JVM design, they are expensive to evaluate. i forgot that in macbook pro you must add your hostname to the /etc/hosts. it� Ignore Z-Ray system requests: Select this checkbox to block requests from the Z-Ray system if they annoy you by invoking the IntelliJ IDEA debugger too often. If starting the Zend Debugger tool fails with the message "Port is busy", specify a port number of your choice higher than 10000.

I would like to add one more case. If we have a number of method breakpoints, then the Intellij will run extremely slow.

What is the expected IntelliJ IDEA 2020.1 (Ultimate Edition) Registry: debugger.watches.in.variables =false, debugger. so it's a "global" issue with JetBrains products on macOS.

This is helpful when a run/debug configuration consumes a lot of resources and there is no good reason to run multiple instances.

Intellij freezes when running debug on Mac : IDEA-157303, Problem was not their before upgrade and I remember this issue exactly like this on an older version although I can't remember which.

Comments
  • Are you running 64-bit IntelliJ?
  • What do you mean by slow? Is it slow to start or slow to step? Did you check intellij-support.jetbrains.com/hc/articles/206544799?
  • @Nathan that off-topic rule specifically says for non-coding tools, since this is about IntelliJ and Java debuggin it's within topic
  • @RayS.Kan you need to be as specific as possible. When is it slow? when it starts, when you are stepping through code. What do you mean? We can't read your mind
  • Problem is solved in deed, yes it turns out this is a duplicate of the problem where localhost name resolution takes quite a long time on macOS. This however is step by step guide answer with some external reference and sums up everything in simple words.
  • I will try it but just a quick question...what has DNS to do with debugging a simple non web app
  • IntelliJ IDEA debugger uses localhost to connect to the target VM, on Mac localhost resolution can take a lot of time (30-60 seconds) in some cases.
  • This would basically mean that this question is a duplicate of the linked one…
  • @DidierL, yes, but it also provides the detailed step by step instructions for the solution vs a link to the external site.
  • Thanks , now debugger fires up in a second.
