CHR on HP server Gen8 SLOOOW

Sun Jun 07, 2020 7:31 pm

SO Ive pulled out all remaining hair trying to get CHR to work with any performance at all.
Ive tried Proxmox, Hyper-V on an HP dl360p Gen8 with an Intel X710 Dual NIC, SSD.
Problem is speeds are slow, I cant get more than 350-400mb out of the CHR. Even with 7 cores assigned they are all pretty heavily loaded, Heavy IRQ use and CPU overall is 60-70 percent at a measly 400mbps.. An old Dual core i3 kicked it ass and maxed out at a gig on bare metal x86. 2 of the Cores are 90-100 percent serving IRQs alone and throughput tops out.
Performance was only marginally better on Hyper-V. Im totally lost and because I cant seemingly reproduce the problem on the bench I have upset customers too.

Router has 900 PPPoE sessions with Simple Queues. basic firewall, MPLS, OSPF.. It should kick the old hardware out of the water. 10g licence on the CHR.

Any ideas? Ive read a couple other reports of HP servers and same issue of slow speed.. Is it the server? Its a Dual CPU Xeon 2.4ghz 8 cores total.

Are the NIC's intel or Broadcom?

Turn off Virtual machine queue in the VM nic settings
