Poor performance and failures when taking snapshots

Hello, I wanted to check out Proxmox and spun up a test environment on an old vmware host we had laying around (Proliant DL380 G7). I successfully installed some linux and windows guests, performance seems fine and wanted to test out snapshots next. I found that when I tried to take a snapshot of my Windows 11 vm, the console for the vm would completely lock up while the snapshot was running. QEMU guest agent is installed (107.0.1.0) and enabled in the vm options. In the task viewer it shows the snapshot starts ok, but then takes a very long time to complete before eventually erroring out. After the task failed the the vm unlocked, I had to halt and restart before I was able to connect again. I tried taking a snapshot without RAM, which did complete but was still slow. The vm is pretty small (64gb disk and 8gb ram) so I am not sure what is going on. My storage is using the local-lvm that was set up during the proxmox install, and has space available. I attached some info below, but please let me know if there are other spots to check or suggestions to troubleshoot.

Code:
