I'd be really curious what the CPU usage is when this is happening, as measured in both the OS and SRCDS. I'm going to bet that the usage is actually low, but the CPU's lack of support for the needed instructions is forcing the engine to do things in more convoluted (and perhaps less optimized) ways. It would be really great to hear from a dev on this topic, though.
It's interesting because many years ago, CS 1.6 started requiring support for a certain instruction set (MMX maybe?), and the dedicated server checked for support on startup. The server quit with an error if the CPU wouldn't work. If this truly is a case of your CPU not meeting the requirements, it seems like they could just make it so the server tells you that and won't start. Also, in my experience, the server console (on Linux) is laggy regardless of whether or not the server is hibernating. It's just always that way.
