Insanely low upload speed

Halloj Patrik and welcome to the UTM Community!

What happens if you disable Web Filtering?

Still, I'm confused by the slowness of the uploads.  Does doing #1 in Rulz provide any insight?

Cheers - Bob

Hi Bob

Thank you! I've been using the UTM at home for a few years and I love the product but I've never had a reason to visit you guys until now. :)
If I disable web filtering I got 800/800 so that seem to be the culprit. Is it normal for it to lower the speed so much?

Configuration for the Web filter is:

Configured my internal network in Allowed Networks
Operation mode: Transparent mode
HTTPS Scan :URL filtering only
Policies: Base policy, nothing else configured

I checked the logs too and saw that the web filter was logging a lot during the upload phase.
Looks like the test is running a series of GET and then POST.

The GET was much larger than the POSTs. So essentially the browser was sending ~700-800 POSTs to the web server.

If I do a test at another site which is using normal ways of testing uploads I get a good speed.

Case closed.

Kind regards,
Patrik

Poor upload speed
Solution

Gigabit fiber here too.  Snort is what's used for traffic scanning.  It runs one process per client I believe.  So if you run a speed test on multiple pc's (assuming you have a quad core cpu or 4 vcpu's assigned), you should be able to saturate the connection.

I get about 400-450mbps down, 500-700 mbps up (depending which site I test from) with web filtering enabled, on a single pc.  Underlying hardware is an i5 6600K cpu with 4 vcpu's assigned to utm.

Here's with just one speed test on one pc.

This is running speedtest.net on 2 different pc's at the same time.

Both get about 400 mbps down, 500 mbps up.  So 3-4 different pc's would max it out.  Your results will different depending on actual core clock speed.  To max it out fully with a single connection you'll need to either get faster hardware or add exceptions to not scan certain traffic.  For my use, a handful of sites are excluded,

Under web protection, filtering options, make sure this is checked.

Utm cpu load as seen by esxi.

Thanks. That test was faster than the one I had before.

This is for my apartment so I don't really need that fast internet. Just wanted something faster than 30 Mbit. :)
