Ok - assuming, as implied, that speedtest results aren’t real.  
Steam application downloads are:

I’ve downloaded ARMA3 4 times.

Procedure - configure av software, launch steam, download application, record results, delete steam downloading and arma3 folder, repeast

Attached photo shows steam downloads under the following conditions:

1. NO AV software installed
2. Kaspersky Secure Cloud Free - protection enabled
3. Kaspersky Secure Cloud Free -protection disabled
4. Other AV software protection enabled 

Results:

1. No av software installed, 99.5MB/s current 100.5MB/s peak (800Mbits/second)
2. Kaspersky SC protection enabled, 44.1 MB/s cur 46.3MB/s peak (370 Mbit/second)
3. Kaspersky SC protection disabled 59.3 MB/s cur, 59.9 MB/s peak (479.2 Mbit/second)
4. Other AV Protection Enabled 57.0 MB/s current, 59.1 MB/s peak( 472.8 Mbit/second)

My questions:
Why does having Kaspersky SC installed result in a 40-60% loss in throughput, EVEN when Protection is disabled.

I think it’s reasonable to assume that AV software has overhead, HOWEVER it’s also reasonable to assume that disabling protection would offset the performance tax.  Why is there still a high degree of overhead when disabled?

Does Kaspersky publish maximum throughput numbers?

Why Not?

Being transparent about maximum throughput as tested in Kaspersky’s labs would alleviate Kaspersky’s support requests.

Ok - so essentially what this article implies is that my speedtest results  are not an accurate gauge of actual internet speed?

I’m not sure what to take from this?

HI @Berny - Sorry I’m new to the forums - I don’t see any suggestions above - am I missing something?  I see some links though - contact support and another thread - is that what you meant?

I enabled hw virtualization but this did not improve my performance.

 

Disableing kaspersky resutled in an improvement, but  kaspersky seems to be still processing packets, even when shields are disabled.

 

Peak I could get with Kaspersky running is 500Mbit down, 800 up.

perfmon indicated that kaspersky was ‘processing’ during the tests, even when shield was enabled.

 

I suspect all av software gets in the way of performance, even when disabled.  A.v.st did the same thing.

My speed drops from

911Mbit down/890 Mbit up

to

380Mbit down/640Mbit up.

 

 

I came here from [another antivirus] because of similar performance issues.

Not using hardware virtualization - it’s disabled. I’m investigating how to enable it.  I thought I had it enabled in bios - perhaps not.  Will check that, ensure it’s enable and showing as active in kaspersky before retesting.

 

Why is impact so high?
I believe my system to be equipped fairly well.
