Multiple files has small size REALLY causes performance issue

I have the real problem with my file syncs between local and icloud Drive,

I am working in data engineering, I know the effection of small file causing low performance and network latency.

But I still had mistake that generate 90.000+ files in my synchronizing folder.

Even Wifi has 35Mb/s uploads, but it still got me xx hours and y restarted time to finish them.

Acctually, the upload bandwidth only xx kb/s.

My laptop, working repositories were stucked.

Again, small files => Performance issue while data reading.
