Does Windows 7 cache directory sizes? (with indexing off!)
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I migrated from a ThinkPad T420s (Windows 7 Pro x64) to a third generation ThinkPad X1 Tablet (Windows 10 Pro x64). The new machine has considerably better SSD performance on paper. After disabling Defender Antivirus in Windows 10, I can also experience the performance difference. However, there is something I don't understand. When showing the properties of my Dropbox directory, the new machine takes four times longer than the old one:
12 seconds (new) vs. 3 seconds (old)
On the new machine, the Dropbox folder is not indexed. So I changed the old machine accordingly. I disabled indexing for the Dropbox folder, rebuilt the index, and eventually I removed the Windows 7 Search feature altogether. Still the difference persists!
Does Windows 7 somehow cache the size of directories? Can I clear that cache? (it can't be the index, since that's cleared already, and disabled)
I also compared how long it takes to get the size of the directory from PowerShell:
Measure-Command { (get-childitem Verzeichnis -recurse | measure-object -property length -sum).sum/1GB }
Here the results are what I expect. On the new machine, the process takes 14 seconds, while on the old one it takes more than a minute.
