why? The same size PS file, one super-large and super-slow, the new build very fast？

[dublove]

My photoshop has been very stuck, my computer configuration is very high.

My ps file, very fast at first, saves the fast moving picture is also very fast, but slowly slow, sometimes it takes 2-5 minutes, the screen will move.

I learned a variety of settings from the Internet, preferences, temporary storage, etc., these are no problem.

Today, I deliberately deleted all the slow large file layers. I used to be 800X13800px. I changed it to 800X800px. I thought it would change to 10M or less, but it is still 429M. It still takes half a day to store, and the movement is very slow. People are speechless.

I have created a new 800X800px, this new file is fast, saves fast, and the operation is fast.

I have seen many people on the Internet also react to the problem of slower ps running. It’s amazing.

Please help me to look at it.

Thanks~

The problem is in your file and it looks like excessive meta data :

According to the release notes v20.0.2 was supposed to deal with that but it does not seem to be affecting this file so the excess data may not be "Ancestor data". The file is slow to open in any application.

Dave,Thank you very much.

The version of photoshop I use is cc 2019 (V20.0.2).

Also, I want to ask, what software is this screenshot you gave? Is phothoshop, it seems to be different from my ps interface.

Hi

The screenshot is the File Info dialogue from v 20.0.2

That version is supposed to address Ancestor metadata (see here) Fixed issues in Adobe Photoshop CC

If it does not, and it appears not to with your file, it will be worth raising as a bug here Photoshop Family Customer Community    where developers will see it (provide a link to your file as you did here)

There is a god given this, it really works.

What I want to ask again is, does adobe have no tools to clean it up automatically?

Edit menu >> Clean up, this is no use

Must rely on external scripts?

function deleteDocumentAncestorsMetadata() {
    //String version of the app name
    whatApp = String(app.name);
    // Check for photoshop specifically, or this will cause errors
    if(whatApp.search("Photoshop") > 0) {
        // Function Scrubs Document Ancestors from Files
        if(!documents.length) {
            alert("There are no open documents. Please open a file to run this script.")
            return;
        }
        if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
        var xmp = new XMPMeta( activeDocument.xmpMetadata.rawData);
        // Begone foul Document Ancestors!
        xmp.deleteProperty(XMPConst.NS_PHOTOSHOP, "DocumentAncestors");
        app.activeDocument.xmpMetadata.rawData = xmp.serialize();
    }
}
// Now run the function to remove the document ancestors
deleteDocumentAncestorsMetadata();
