Insanely low upload speed

Question

Hi 
 I am running UTM at home but I am experiencing really low upload speeds. 
 Version: 9.601-5 Hypervisor: ESX Adapter type: vmxnet3 NIC: Intel QoS: Disabled 
 Connect my computer directly to my fiber converter: 900+Mbit download 900+Mbit upload 
 Sophos with IPS enabled: ~300Mbit download ~30 Mbit upload 
 Sophos without IPS enabled: ~700 Mbit download ~30 Mbit upload 
 The test I am running is downloading a file over HTTP so I have a hard time thinking that my rule base is the problem. 
 Any ideas? 
 Kind regards, Patrik

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?

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.
