Hey!
I’m sorry you are having this issue. Could you provide some additional information so that we can try to better help you?
Which version of Postman? (Desktop, Browser etc.)
Can you check if you have a lot of history saved in the app? (in the History sidebar)
Yes, same issue here… using Postman desktop, REALLY slow since I updated to Windows 11, I tried updating to the latest version but it’s still the same

Hi, I’m getting the same issue with the Windows 11 desktop app.
The app takes long to open for the first time (about a minute); after that, closing and re-opening is quick. Updated to latest version yesterday, and it didn’t fix the issue when I opened the app this morning.
App info:
Postman for Windows
Version 9.17.1
UI Version 9.17.1-ui-220427-0630
Desktop Platform Version 9.16.0
Architecture x64
OS Platform win32 10.0.22000

I don’t know if this is only Windows 11 related, because I’m having problems that sound similar as the problems in this thread with windows 10 too.
It works fine for a minute after opening and after the minute the app freezes but doesn’t say it’s not responding. When I try to open task manager, the task manager is not responding. Luckily I can close postman from the X on the upper right corner. After closing the app, task manager starts to work normally.
I was running old version of postman, but now I got it updated and the problem still continues. I also uninstalled the app and reinstalled with the newest version I downloaded today from postman website, but still after about one minute of usage the app freezes completely.

Came here because I had the same issue. In my case, I was able to solve it by disabling Hardware Acceleration: Setting up Postman | Postman Learning Center
Hi, I’m also having this issue and it is really painful when I try to demo my API in a video chat.
After a fresh Windows boot it takes 2-3 minutes to see Postman window. Subsequent starts are almost immediate. I disabled HW acceleration, and deleted the cache, but no success.
PM Version: 9.19.3

Any suggestion/fix would be appreciated. Thanks.
I have same issue, i deleted and download and installed again but , it is very very slow. Even it is not useable.
My Postman is quite slow. Clicking tabs and changing to different tests takes close to a minute to open. I followed some instructions i read in the thread to go to
View-Developer tools…and this is the report. Could you please advice.
any new update on this issue? I have the same problem.
I takes 2 full minutes to open the app (blank screen) and +40 seconds to load the interface. From that point the app works normal.
Version: Postman for Window 10.19.7
OS: Windows 11 Pro 22H2 22621.2428
Proc: AMD Ryzen 9 5900X
RAM: 64GB
Also tried with POSTMAN_DISABLE_GPU=true in system environment, delete cache, reinstall app and it had no effect.
From what i see in the application log, is that it take a lot of time between this points:
[36720][1698254987344][main][info][“userPartitionService: users global meta:”,{}]
[36720][1698255109838][main][info][“RuntimeIPCAgent~started: Success”]
i can provide more logs if needed.
