That looks normal.  Did it really take three minutes for the USB speed test to complete?

 

You might want to look for a new network driver.  Were you doing anything heavy with Internet Explorer the first time?

The Latency Test didn't complete by itself, I stopped it because you said it should take less than 30seconds.

On IE I only had a light gmail account and newsletter subscription page open.

Guess I wasn't clear.  Latency Monitor runs until you tell it to stop.  Idea was to start it then run the USP speed test then stop Latency Monitor to see if something bad is happening.   Expect your network adapter probably needs updating so leave it off while running the speed test.

[RKinner]

We got a few page faults from Windows Defender but 16 seconds isn't that bad.  What speeds did it show that time?

[hmp3]

started at 4 ended around 1.45mb

[RKinner]

Write or read?

[hmp3]

Write.

[RKinner]

That's about normal for write.  The drop in speed during the write test is something I see on one of my drives too.

What did it say for read?

[hmp3]

Read 14-28

[hmp3]

Write has previously been 16mb, as written in previous posts.

How can it be 16-18 then next test 8-10, then 4-6?

Edited by phickspc, 09 November 2018 - 07:38 PM.

[RKinner]

That's what we are trying to figure out.  We got decent results with the network adapter turned off but we did see Windows Defender sticking its nose in.  Can you pause Windows Defender and repeat the test with the network adapter off?

[hmp3]

Windows Defender wasn't turned on at all.

I searched for it in Process Explorer, but the only trace it found was svchost and when I paused that the computer froze until I resumed it again.

So I looked in msconfig and unticked it's box in the startup tab, restarted and double checked it was disabled in services.msc (it was disabled).

Disabled Network Adaptor then started the tests.
