Re: "OneDrive Is Updating Files" never ends and has high CPU
Mike Williams: I think you underestimate the mental capabilities of paying customers. The googled linked answer was valid until the site design was changed. See attached screenshot. The "new" way is to open the context menu to show the Manage Storage view but this shows only file sizes but not the file counts. Do you have an answer to my question which is not outdated?4.4KViews0likes1CommentRe: "OneDrive Is Updating Files" never ends and has high CPU
Mike Williams: 300K files is not that much. My main workload are memory dumps and ETL files which comes with thousands of pdbs per zip. The previous product I used was Synplicity which allowed me to skip .pdb, .dmp, .etl from syncing. I always get compressed files so I can easily sync the compressed files and unzip them locally. With OneDrive For Business the world was simplified. Now everything is synced and I cannot prevent it. I did ask our IT and they said that feature is there but only at tennant level. In the new world it looks like I need to copy the data again somewhere else and uncompress them before OneDrive gets a chance to overflow. How can I check with OneDrive how many files I have in the cloud? The Storage explorer only shows files sizes but not counts. If I look at the ObfuscationStringMap.txt file I find 174647 lines which should mean that I have at least so many files.4.4KViews0likes3Comments"OneDrive Is Updating Files" never ends and has high CPU
I have two machines where one has a large bunch of files (ca. 360 GB) while the other machine has only a small fraction of them downloaded. After reaching some point OneDrive does stop syncing anything. When looking at the machine with high CPU I find that most time is spent in KernelBase.dll!LCMapStringW by the sync engine. Procmon and ETW shows what happens: Enumerate a file on my drive Call LCMapStringW with the file name read/write SyncEngine-2020-08-03.2209.25372.179.aodl Goto 1 Between each file enumeration ca. 2.5s! are spent in LCMapStringW and sync engine. That is an insane amount of CPU to walk through the file system. The aodl file seems to be some encrypted SQL database which I cannot read. Has OneDrive for business scalability issues with many small (ca. 10K) files?4.6KViews0likes5Comments
