Clarification for constant hard drive I/O

[woolongdong]

Hello Adguard Community,

I tried searching for that topic but it's a bit tough because there is some russian threads I could find (but I'm not a russian speaker and google translation wasn't really good) and of the english threads I found I couldn't really get a clue. Also searching for SSD isn't possible so please bare with me if there was already some explanation for this.

I realized in the windows resource monitor there is constant I/O on my system hard drive (a SSD in my case) from Adguard/AdguardSvc to files like:
C:\$LogFile (NTFS Volume Log)
C:\ProgramData\Adguard\adguard.db
C:\ProgramData\Adguard\adguard.db-journal
C:\ProgramData\Adguard\SSL\cert.db
C:\ProgramData\Adguard\SSL\cert.db-journal

According to Kaspersky this sums up to several GB of disk usage a day. According to Process Explorer I can see around 49GB of I/O Read Bytes and 3.4GB of I/O Write Bytes after around 5hr of PC usage. Can someone please explain to me whats going on here? I'm afraid this will make my SSD wear a lot faster because of this.

With kind regards,
Woo

I also have an SSD, so am also interested in this topic.

So according to the Disk & Network tab within Process Explorer there is way less I/O on both the network and the disk (only 6MB read/97MB write for the same duration). It looks like those I/O Read Bytes are somehow misleading because Kaspersky would show it as regular disk usage (which seems to be completely wrong and made me curious in the first place). I can't explain tho why the total I/O is significantly higher than network + disk I/O.

Same too, good question.

The reason for this is that AdGuard uses a so-called "control device" for the communication between the network driver and the main process. This "control device" is a virtual disk so it may be counted as IO by Kaspersky.

Nevertheless, it won't hurt if we check if there are any unnecessary writes to the databases you mentioned.
