I don't have a 'rename' operation, but I've clocked my thing at doing
about 3,000 writes per second, under good conditions. That's on a
cluster of five machines, can't remember the precise specs, but
they've got
But then, it's running on 2GHz Opteron dual-core systems with 8GB of
RAM, so you'd hope for a lot.
The live platform will soon be ten nodes, half of them in London,
half of them in Dublin, with a dedicated Ethernet link between them
with a ~8ms round trip time.

My nodes totally and utterly trust each other.

Nope.

Yep! But that could easily be fixed. It's just not a problem in the
current target application.
Askemos is very interesting, but the security stuff isn't needed in
my case ;-)
