@chris. Thanks. I wil keep you update if I find something
@Joe. I am not telling this is a bad number. I am just telling this is
still not enough for us ( in order to limit the number of nodes) ;o)
If I look at the last bench, version 0.6.2 is around 13000w/s
I should/would be able to reach 10000w/sec (in fact this is almost
the case in non virtualized env.).
I am just trying to understand where is the bottleneck.
What do you mean by "N+1 scaling"? Not sure to understand the expression.
Thanks.
