An XO-1 is a tiny, tiny server. Bear in mind I would not expect it to
handle much more than 20~30 users.

Additionally, the USB-Ethernet dongles cause a ton of IRQ noise, so if
there is a bit of traffic, the CPU gets swamped with handling network
activity. One of the nice things of modern network cards (PCI, etc) is
that they have gotten really good avoiding raising IRQs, doing DMA,
etc. You cannot do any of that with a USB-Ethernet.

I assume you ran xs-swapnics at some point?

that means that the domainconfig didn't work.

Any logs from ejabberd itself?
