We're using an ADLS gen2 blob container for our ETL pipeline.
There's one folder in particular that is our "landing" point where we have new files being generated (5 / hour) via small append operations. Those files get moved off and processed, but we usually only have ~5-10 files in that folder at any given time.
Over time, this folder has become increasingly slow to open (list the files) via storage explorer and the azure portal console.
Viewing the folder took ~70 seconds just now. Sometimes it's slower, sometimes its faster. Is this a known issue? No other folders have this issue.
I'm wondering if we should be avoiding this usage pattern in ADLSv2 and create new folders instead of re-using the same one? Did I miss something in the documentation?
Thanks.

Do you have blob versioning enabled?
Apologies for the delayed response. No versioning enabled.
Note, I just recreated the folder and it loads instantly again. Not a great long term solution, but at least I have a workaround.

Hello @Kyle M ,
Thanks for the question and using MS Q&A platform.
As we understand the ask here is why this one folder is taking more time then others , please do let us know if its not accurate.
Well did a quick check on my side , I do not see any issues . Its very difficult to callout as to what is happening with that folder without actaully looking into the setup . I mentioned that you do have the workaround and but if you want a deep look into into this , please work with the Microsoft support . if you have a support plan you may file a support ticket, else could you please send an email to azcommunity@microsoft.com with the below details, so that we can create a one-time-free support ticket for you to work closely on this matter.
