[Mono-list] Network Interface // Performance counters

[Torstensson, Patrik]

Hi guys,

Just to be clear, performance collectors are not writing to the registry
all of the time. The performance counter key is just a shortcut to a
in-memory server that polls all performance monitor extensions for new
performance information. Don't ask why they added the possibility to
poll the registry for the performance information, maybe a old design
flaw.

It shouldn't be that hard to add a wrapper that checks what counter has
been requested and polls the devices instead.

Cheers,
 Patrik
