<ul></ul><p>I should also point out under 2.4.3 that IBRS isn't enabled:</p>
<pre>
[2.4.3-RELEASE][admin@trogdor]/root: sysctl -a | grep ibrs
hw.ibrs_disable: 1
hw.ibrs_active: 0
</pre>
<p>Also the CPU is passed through from KVM as type "host" which means all features should be present (as shown in the output in my original post)</p> pfSense - Bug #8463: Performance Regression in 2.4.3 under KVMhttps://redmine.pfsense.org/issues/8463?journal_id=363902018-04-19T04:04:33ZAnonymous
<ul></ul><p>As suggested on reddit I have also done a fresh install of 2.4.3 and then applied the backed up configuration. This was in an attempt to see if something during the 2.4.2 to 2.4.3 upgrade might have caused the issue.<br />However with a fresh install, the issue persists.</p> pfSense - Bug #8463: Performance Regression in 2.4.3 under KVMhttps://redmine.pfsense.org/issues/8463?journal_id=363992018-04-20T19:56:59ZAnonymous
<ul></ul><p>If I change the cards from being vtnet to em0 (i.e. remove the VirtIO ethernet card in Proxmox and replace it with the e1000 card) then I get performance back where I expect it to be.</p>
<p>So this is a fix.</p>
<p>The regression appears to be in the vtnet driver/codepath.</p> pfSense - Bug #8463: Performance Regression in 2.4.3 under KVMhttps://redmine.pfsense.org/issues/8463?journal_id=400322019-02-21T02:07:07ZAnonymous
<ul></ul><p>In the end I moved to FQ_CODEL so this ticket, while probably still an issue, can be closed.</p> pfSense - Bug #8463: Performance Regression in 2.4.3 under KVMhttps://redmine.pfsense.org/issues/8463?journal_id=414922019-08-14T13:19:29ZJim Pingle

<p>For example, on 100 mbit WAN i am trying to apply 50 MBit limit:<br /> altq on pppoe0 fairq qlimit 1000 bandwidth 50Mb queue { test } <br />queue test on pppoe0 bandwidth 50Mb priority 1 qlimit 1000 fairq ( default )</p>
<p>Which ends up WAN interface showing 50 Mbit during upload, LAN shows 25 Mbit, and actual data stream on receiver is 25 Mbit.</p>
<p>I have tried to change em0 to vmxnet3, but result is the same.</p>
<p>When I try the same shaping on non-pppoe interface then it works normally.</p> pfSense - Bug #8463: Performance Regression in 2.4.3 under KVMhttps://redmine.pfsense.org/issues/8463?journal_id=500072020-12-19T00:16:34ZAnonymous

<p>Please open a new ticket.</p>
<p>This ticket</p>
<p>a) Is closed<br />b) Is about VirtIO interfaces, not vmxnet3<br />c) Is about KVM, not VMWare</p> pfSense - Bug #8463: Performance Regression in 2.4.3 under KVMhttps://redmine.pfsense.org/issues/8463?journal_id=500082020-12-19T01:08:30ZAlexey Ab
