I saw the presentation "Virtualization of Linux Servers" at
OLS last month and it had some nice comparisons of Xen
performance vs a lot of other virtualization/container


As always with benchmarks, there are questions to ask and
points to quibble, but overall Xen looks quite good...
except on Dbench.  Has anybody else run this benchmark
on Xen and gotten better results?  If not, any thoughts
on why Xen (and all virt solutions) would do poorly on this
benchmark?  And whether Xen can/should be fixed?

Thanks... for the memory
I really could use more / My throughput's on the floor
The balloon is flat / My swap disk's fat / I've OOM's in store
Overcommitted so much
(with apologies to the late great Bob Hope)
