Operations that take less than a second with either workload running alone can now take many seconds, sometimes the better part of a minute! Is this some limitation of the qemu device model? -- "Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it." - Brian W. Kernighan
