Lightroom classic starts slowly, freezes for quite a while

[冬杨27842135]

Everytime my lightroom classic (on windows) starts really slow before loading files on the hard drive, it freezes for quite q while, reading nothing. The network is not used, the CPU is idle.

I suggest adobe adding some tracing program to this app to help diagnosing this problem.

Hi there,

Sorry that Lightroom Classic is freezing and running slowly while loading. 

Would you mind checking that you are using the latest version of Lightroom Classic from the Creative Cloud desktop app? See https://helpx.adobe.com/lightroom-classic/kb/keeping-lightroom-up-to-date.html

As Lightroom is running slow, could you please try turning off the GPU option from Lightroom's preferences? Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor", restart Lightroom and let us know if it helps?

Also, Does the app freezes while performing a specific task? To get started, you may checkout the steps mentioned here: https://helpx.adobe.com/lightroom-classic/kb/lightroom-basic-troubleshooting-fix-most-issues.html 

Thanks,

Akash

It seems turning off the gpu helps. I will keep watching to see if this is consistent.

That's great. Glad to know it worked. If you have any other query or need further assistance, feel free to get back to us anytime. 

Thanks,

It's not working. It seems the first launch of lightroom after a system reboot is the slowest, disregarding whether I turned the GPU off or not.

I have the latest version of Windows and lightroom.

What anti virus is in use?

[冬杨27842135]

The built-in Windows 10 anti-virus software. No other.

If you have your cell phone attached via USB cable, disconnect it and see what happens.

[冬杨27842135]

No cell phones or cameras were attached during the startup of lightroom.

[冬杨27842135]

I suggest Adobe to add some tracing code to lightroom to help debugging this type of performance issue. Or, give me a thread dump program, and I will dump it for you guys the next time I start lightroom.

[冬杨27842135]

In fact, I will dump this one for you the next time I restart. I will generate a *.dmp file. Your programmer can analyse it using WinDbg.

Do you have a Logitech mouse or keyboard, and have you installed Logitech Options?

Go to File > Plugin manager and check if there is a LogiOptions plugin in Lightroom, if there is, disable it.

This plugin in known to cause very long startup times.

[冬杨27842135]

Thank you! I do have this plugin. I will disable it.
