I have a synology running SMB2-SMB3 and from one windows 10 computer it takes a few seconds to search for a file name in a folder that has 1264 files. on another windows 10 computer it takes 10-12 minutes. what could be wrong on that slow PC?

ipV6 is disable on both PC and server

adding a 'DirectoryCacheLifetime' registry key didn't help

    Al,

    Well, I've been fighting search for years. Maybe it's just me, but I haven't had a good experience since the Win2000 days.

    Are you searching file contents?

    I traced a network search with Process Monitor and my Win10 laptop is still calling the SearchIndexer. Run procmon and see what's being called on your machine.

    I gave up on Windows search long ago. I prefer Agent Ransack. The free version doesn't have an index, but that's fine with me.

    I have a synology

    What is a synology? A NAS? Does it authenticate with local or domain accounts?

    Is there anything different with the indexing service configuration on the 2 pc's? Open a command prompt and do a "dir" command to look for a file. Does it take the same amount of time on the pc's?

    Are all machines on the same subnet? Does the "long running pc" have problems copying files from other machines? Do you have another pc where you could set up a test share and try something similar. Or put one large file on the synology and see how long it takes to copy.

    Is there sufficient memory/cpu on the "long running pc"?

    Hi Moto,

    yes, Synology is a NAS.

    when i search at the command prompt it finds is instantaneously.
    the one that searches quick is connected over a VPN, but yes, to the same subnet
    copying happens fast, it's just searching. there's no difference in the indexing options on both PCs. i cannot add a mapped drive to the index.
    on the slow searching computer the C drive has 34% free, 76GB. Memory is 84% utilized

    Thanks,
    Al
