Fresh install of Rocky 8, networking is not working correctly

I am "upgrading" a server from CentOS 7 to Rocky 8. This server is a 1U Supermicro SYS-1029U-TRT, works as part of an HPC, and has two Ethernet and one Infiniband networking interfaces. One of the Ethernet interfaces is for the HPC, the other is used for the server room network and Internet access. After bringing up a VM copy of the CentOS server I started a fresh install of Rocky 8. I reused the previous partition table and mdadm RAID that was already configured and formatted each partition. After the install and initial set up of the networking interfaces the server is exceptionally slow when dealing with any network traffic through the "external" interface. This issue was never evident under CentOS and has multiple symptoms.

• DNS queries do not get completed. This is seen especially well when running a ping on a host on the local network or attempting to download a file from the Internet or a local web server via curl or wget.
• Pings to and from the server, using IP only, will either fail or start working after some, usually about 4, packets fail.
• SSH connections to the server mostly fail with some attempts getting a password prompt but the login never completes.

I have attempted a number of troubleshooting steps with no apparent fix yet.

• I verified that the IP settings, routing table, and resolv.conf were all correct.
• I disconnected both of the HPC network interfaces. I also tried with the interfaces connected but deactivated, with no configuration, and with them connected and configured.
• I verified that the Ethernet drivers were correct for the hardware. The system includes two 10Gbps Intel X540-AT2 interfaces which is using the kernel's ixgbe driver. I also downloaded and installed the latest version of Intel's driver.
• I verified that the switch port is properly configured, including the VLAN and MTU settings.
• I tested the other two interfaces via ping both to and from the server and both showed no issues.
• I disconnected the interface from the usual switch and used a new cable to connect it to a nearby switch on the same VLAN.

None of those steps changed a single thing. I'm out of ideas and am looking for further possible reasons for why this is occurring. If any information is needed I'll gladly add it as requested.

A previous issue that was not reported when CentOS 7 was installed is that sometimes a SSH connection would "pause" for up to a minute before being usable again. This is similar to the current issues to make me think this is a hardware issue.

Here are some ip command outputs, ip a and ip route, to show how things are configured. Also when configuring in nmtui I enabled the "Never use this network for default route", "Ignore automatically obtained routes", and "Ignore automatically obtained DNS parameters" settings on the eno2 and ib0 connections. None of these settings are enabled on the eno1 connection.

Edit1: Added more info, the CentOS issue.
Edit2: Added requested ip command outputs and some nmtui settings.
