Speeding up "verifying integrity of existing..."

[eLPuSHeR]

Hello.

I don't know whether this is doable or not but that stage(s) TAKE AGES on my SATA II hard disk. I don't know wheter the script is reading/verifyng hashes or whatever but as I have said it takes ages (I know my hard disk is not the fastest one but).

Chipset is Intel X99 with Intel AHCI driver.

I have set a folder exclusion for Windows Defender. Now, instead of 2h it takes one hour and a half.

I will try with standard ms ahci drivers this afternoon.

It's only 1-2 minutes, for me. This is on a USB 2.0-connected magnetic hard disk.

Even 1.5 hours is abnormally long.

On my server it takes one to two minutes, even for the ~4.5 GB updates for MS Office (on internal SATA disk).

Defragmenting the files could help, but since the time span you told us is so much larger, it could be that your disk has some issues reading some sectors (or is even dying). You should check its SMART values with a program like CrystalDiskInfo and probably do some performance tests with the drive.

Taking about 5 minutes here.

Hello.

First of all, thank you very much for those suggestions.

On my work's computer, (Intel i7, 7th gen), the full process takes usually around 15-20 minutes. I am using a SATA III drive there.

I am going to do some integrity, surface tests on my SATA II hard disk although it appears to be fine.

This is what winsat says about performance.

Disk is totally defragmented and seems in working order.
Time to go to sleep. I will do more testing tomorrow.

Hello.

I have just created a whole WSUS installation from scratch (At my work's PC).

Total time 22 minutes. Good.

Could it be I was previously using the minimizeondownload=Enabled option?

I will recheck it after lunch on my main SATA II PC.

[boco]

There is an OS "foreground boost" for the currently active window, yes. The only thing you could do is trying if it makes any difference without that option.

Do you have any software that manages process priorities (like Process Lasso, for example)?

Please monitor the C7 errors on your HDD, may be a cable/connection problem.
Plus the more threads your CPU has the more files are checked simultaneously which is major stress for a HDD and actually forced me to move files to my SSD (HDD head sounds were not sounding healthy to me)
