I have rebuilt two HP DL328 G5 servers with Windows Server 2012 R2 instead or Windows Server 2008 R2

Everything seems to be working normally but ping response times seem much worse than before

Ping reply times were always <1ms but now  5 to 10 % seem to be above 1ms

Same guest workloads just change of operating system and using Microsoft teaming its two NICs instead of HP Network Team

Is this to be expected when using a more advanced operating system?

Not te be expected. Maybe the firewall is more tight or nic drivers are not spot on.

On a G5? I'd definitely expect that. The network stack in 2012 and 2012 R2 was significantly re-architected to support SMB3, hosting virtualized workloads over SMB, improved IPv6, and a feature you are using...native NIC teaming support.

But because of that, NIC drivers need to actually support the OS. The newer OS will perform "okay" with OOB drivers, and slightly better with older 2008/R2 drivers. But because the network stack is now having to use shims to support the older drivers, there is some overhead and your performance won't be as good.

Just one of the drawbacks of running a new OS on hardware that isn't supported. You wouldn't see this issue on a G7 or G8 that officially supports and has native drivers for 2012 R2.

Interesting information

However the HP Service Pack for ProLiant (SPP) W2K12 R2 Supplement for SPP seems to have updated drivers for DL380 G5 server components so I thought they should work better than those on Microsoft's Installation ISO

It is still not an optimized driver. As you can see here, there is no support for any G5 servers for 2012 R2. A few G6's, and G7s and G8s, but no G5s.

I will check our DL380 G7 server after it is upgraded to Server 2012 R2

One of Microsoft's Windows 2012 R2 server updates, KB2919355 I think, seems to have fixed this issue

Ping times to my servers seem similar for Windows 2012 R2 and Windows 2008 R2 now
