slow network transfer rates copying or moving small files QNAP Synology

Do you have a QNAP NAS?

can you copy or move very large files with gigabit speeds like around 100+MBps? (megabytes per second).
but when you copy small files the transfer rate drops to 10, 5, 1, or even 0kbps (kilobits per second).
sometimes sitting at zero for minutes?
If you use the app CX file explorer on your phone and the transfer rates are way higher than on your computer them the problem is on the computer.
have forums been telling you that this is normal? WELL IT'S NOT! they just don't know what to tell you.
I'd like to be able to give you an exact reason why this is happening, but it may have multiple causes.

Here's what I suggest:
check all cables and devices support the speed you are trying for.
check your MTU, is it the same on all devices?
drivers, updates, lan card settings, yadda, yadda, yadda!
check SMB versions on all devices.
disable encryption.
disable any compression.
check share permissions.
disable server signing.
if joined to a domain is the device still joined (this was an issue for me).
disable anti-virus scanning the NAS drives by letter and UNC (also an Issue).
If .jpg transfers are slow are thumbs.db accessible and changeable?

I read somewhere that creating a new profile can fix some NAS issues. in my case I logged in to my computer as a user that had never logged in before and mapped a drive. then logged out and back in as me and suddenly the speed issue is gone.

I did all of the above to get my QNAP transfer rates to what they should be.
My synology was having issues but not as bad. disabling virus scanning fixed the issue for it.

Windows 10 Strange problems recently appear caused by microsoft ransomeware protection

 recently I had some strange issues crop up that made no sense, and if they generated errors at all they also did not make sense.

First was this one: https://robert.guildig.org/2023/03/nero-burning-rom-does-not-see-blank-or.html

the next one happened this morning. I was making a backup to blu-ray (which worked fine).
I (being a bit old school) went to a command prompt and attempted to issue this command in a folder the path of which is c:\users\username\documents\backup

command was as such dir /s d: > backup24.txt
simple right?
no! it comes back with file not found (I don't remember the exact wording).
What the heck! file not found?! it should just create the file.
now I think I'm losing my mind because I've been working on computers since dos 2.11 I've done this MILLIONS of times. after confirming I haven't suddenly developed dementia (by googling the command), I try creating the file in the GUI (which works) and run the command again.
the results:
not enough space on the disk
there's 759 gigs free!

Remembering what happened yesterday I go in to ransomware protection and sure enough CMD.EXE is blocked from accessing that folder and a bunch of other folders (most of which I never use).

I unblock it and the command works perfectly.

If the command had come back with "access denied" I would have dealt with it differently, but the unconventional errors that did not match the actions being prevented was not helpful.

I don't know when Ransomware protection was installed. my googlefu says possibly sometime in 2019, but that it was not activated by microsoft until recently (because I didn't activate it or even know about it). All this worked in september 2022.

Nero burning ROM does not see blank or any disks in burner

nero 10
problem started sometime after 9-23-2022 (last time I burned disks).
same Blu-ray/DVD/CD burner.
same media I have always used.
Reads all media just fine.
windows shows disk changes.
windows shows when disks are blank.
connect an external burner and same issue.

nero 10 suddenly stopped seeing the drives at all.
uninstalled nero 10.
purchased and installed latest version of nero 2023 25.0.1.4.
Nero now sees the drives.
place empty disk in drive nero does not see disk, but windows does.
updated firmware on drive. rebooted, nothing changed.
uninstalled drivers for drive, rebooted, nothing changed.

tried burning with windows (never did that before always used nero) takes forever and doesn't complete because it says I need 816 PB and disk is only 4.7GB or 25GB. data is 4.3GB.

contacted Nero and they were no help. found this article but not by searching for the symptoms. 

windows 10 ransomware detection was the problem.
you have to go in and allow blocked nero apps.

there was no warning or popup that a block had happened it just suddenly stopped reading or seeing disks.

very frustrating.
