Same question...

VS2019 Preview starts up in 5s. Intelij IDEA needs more than 50s.

Pranav, 

I believe blaming the product is not the most effective way to troubleshoot the issue. Let's focus on the case itself. 

Am I right that you added IntelliJ IDEA's process to the list of exclusions of Windows Defender as it is described here

Do you have the same disk I/O speed on both machines? How fast the local drive is on both machines?

@Konstatantin,

It's a dual-booted Laptop. Means yes, I have the same disk I/O speed on the same machine since its the same machine.

No, I have tried the Windows Defender steps u mentioned. Because I'm busy am trying to solve another IntelliJ Tomcat problem through this forum and other forums.

 

But I highly doubt that exclusions of IntelliJ will make a dent. I will try and comment later.

I also see that intellij is usually starting way slower on windows machines compared to ubuntu machines.

After upgrade to intellij 2019.2 and excluding intellij process and project files from windows defender it drastically reduced on my windows machine (from like multiple minutes to something between 30 and 60s maybe?).

But still is my ubuntu machine way faster, where intellij usually boots in something like below 15seconds or so.

Plugins are the same on both machines but I haven't checked the difference in IO speed, although both have SSDs and the ubuntu one is a few years older...

Linux FS is much faster than on Windows or even on macOS. Antivirus running in the background on Windows may still affect the performance even when you exclude IDE files and folders.

@Konstantin Annikov and @Serge Baranov, I have done everything you have asked but using IntelliJ on Windows is a painful task. Sure, that there is an improvement in the startup time But building and running, is a very painful time-consuming activity. Sometime IntelliJ stops responding at all. If we keep continuously working IntelliJ starts responding instantly to actions like run, build, But when doing the exercises and stopping and doing some exercise again while listening to a presentation or a recording of an online training session, IntelliJ freezes and stops responding and become very delayed in responding.

Every specific case should be examined separately as there are a lot of different reasons for such behavior. Please submit a ticket at https://intellij-support.jetbrains.com/hc/requests/new with the problem details and share the complete logs folder compressed including ThreadDump directory, after reproducing a problem.

As a Ubuntu 19.04 user, the recent update of 2019.2.1 is a little bit faster at opening.

I hope this improve over time. Big hope.

@Konstantin Annikov,

                          Although not regarding the slowness of IntelliJ, complete logs folder compressed have been submitted at https://youtrack.jetbrains.com/issue/IDEA-218222

Thank you for the update. Assigned developer will examine it soon.

Excluding a process name from antivirus protection in Windows 10 did work for me eventually BUT I had to exclude "idea64.exe" AND "fsnotifier64.exe" which was suggested in one of the discussions.

This did the trick for me, now IDEA starts and loads a project super quickly :)

For future readers: anti-virus exclusions fixed the startup slowness problem.

On my Windows 10 Pro, Intellij Ultimate 2019.1.3 takes 2 minutes to lunch.

On my Ubuntu 19.04, Intellij Ultimate 2019.1.3 takes 50 sec to lunch.

Intellij is not improving when it comes to "being ASAP".

Do I need to create a bug report/feature request for this?

That was not that helpful.
 
IntelliJ is slow. And everyone knows about it.
