Windows OS: Windows 10
Hardware Information
CPU: AMD 3700x
Main Board: Gigabyte B450 Auros M
Memory: Corsair Vengeance LPX 64GB (4x16GB) 3200MHz
Hard Drives: WD30EFRX
PrimoCache Version:
Screenshot(s) of your PrimoCache's main dialog showing cache configuration and statistics:
I added three graphs which are PrimoCache version, Cache Configuration, and Defer-write Mode setting.
Problem Description:
I set the latency for defer-write as 10 seconds.
From the description, Write Mode Idle-Flush will flush the defer-write bytes when the latency is reached or the system is idle.
However, from my experiment, Primocache 4.3.0 doesn't flush defer-write bytes after latency time.
For example, if I start a download of a 1GB file, it doesn't flush the bytes even after 20 seconds.
If I switch the Write Mode to Native, I can see the hard disk starts writing after 10~11 seconds.
Is this a bug? or this is the expected behavior of the feature?

Its not OR, its AND.
It will write your data when the system is idle, but not before the defer-write time has expired.

The description for Idle-Flush is
"In addition to the behavior of Native mode, it will also flush all deferred data to disk when Windows is idle."
It doesn't look like AND.
Besides, if you set Latency to a longer value, say 60 sec, you can see PrimoCache flushes the defer-write before Latency is reached.

You are right. The logic is OR, not AND. Can you fix the error in the images you uploaded? The images cannot be displayed. Thanks.

Can you tell me which one you can't see?
I can see all of them from my browser (Edge).

I'm sorry for the late response. All images cannot be displayed. The host imgur.com initially showed that there was an error in the image, and now shows a http 409 error. Can you upload these images to the forum instead of using imgur.com? You can edit your post and then click the "Attachments" tab to upload your images and then place them in your post. Thank you.
