Slow startup on Windows: splash screen appears in more than 20 seconds Follow
IDE startup takes more than 20 seconds to show the splash screen for the first time, subsequent start is usually much faster.
- Antivirus software with the real-time monitor such as Windows Defender is working on the computer.
Windows Defender slows down IDE startup by scanning its files. The scanning has become much slower recently for the yet unknown reason.
Add IDE process to the exclusion list of the installed antivirus. Here are the steps for the Windows Defender:
- Go to Start > Settings -> Update & Security -> Virus & threat protection -> Virus & threat protection
- Under Virus & threat protection settings select Manage settings
- Under Exclusions, select Add or remove exclusions
- Select Add exclusion and add the "<Your IDE Process Name>", "fsnotifier.exe", and "fsnotifier64.exe" executables.
<Your IDE Process Name> is one of the following process names depending on the IDE:

I also needed to add an exclusion for "fsnotifier64.exe" so that the startup-windows (which displays the startup progress bar) showed up. I'm not sure if this further accelarted the start-up performance in total.
The same exclusion had to be done also in Malwarebytes on Windows. Now it is back to usable again.
Thanks for this tip.
Excluding rider64.exe and fsnotifier64.exe didn't help: Windows Defender was still scanning something and it took long for the Rider's splash screen to show up.
The following gist helped and now Rider starts quickly: https://gist.github.com/nerzhulart/89c6a376b521a6e7eb69a04277a9489a
Surely whitelisting these processes leaves you open to anyone just using these process names?
This is hardly a solution and whitelisting processes should be an emergency workaround only.
You should fix whatever is causing this behaviour in the first place, because other, much larger software packages do not run into similar problems.
Exclusion of .exe files didn't help in my case, BUT excluding a folder of IDE worked well. Now Windows Defender doesn't scan it
Ah, yes, finally!
These hints were helpful. Especially the link to the gist from Mikael Koskinen .
I agree with the security issue. Why do other software packages not have similar issues ?
Thanks for these tips. My webstorm now runs much more faster.
Small correction - webstorm64.exe duplicates on the "process names" list.

As suggested above, also excluding "fsnotifier64.exe" worked for me on Windows 10, now IDEA starts and loads a project super quickly :)
THIS TOTALLY MADE A DIFFERENCE! I have a High End Gaming PC that I also use as a work station, and it was worrying that was taking up to 60s to load. Added all of those as well as the fsnotifier64 made it load in 3s! Thanks a lot!
This doesn't seem to help me on Windows. I allowed all of the processes suggested and that didn't make a difference.
I even temporarily disabled Windows Defender entirely and it still takes 2-3 minutes to get through the "Reopening files" loading screen.
Brettlehrer If the project files are on the fast local disk and it takes 2-3 minutes, please file a ticket with the logs (Help | Collect Logs and Diagnostic Data) and the CPU snapshot: https://intellij-support.jetbrains.com/hc/articles/207241235.
Peter Wake and Markus S. :
"When you add a process to the process exclusion list, Microsoft Defender Antivirus won't scan files opened by that process, no matter where the files are located. The process itself, however, will be scanned unless it has also been added to the file exclusion list." - Configure exclusions for files opened by processes
datagrip64.exe shows up twice in the list for some reason. Might want to edit that.
It has been insinuated that this issue does not occur on Linux but it does. On a completely fresh install of Ubuntu 20.04, PyCharm 2021.1 is incredibly slow to start (i.e. 30+ seconds) the first time. Subsequent times are faster.
