b)sudo ./qpid-perftest --sync-publish=false --durable=true
This is the same test as above and should be --sync-publish=true
--durable=false.
The reason I'm asking about these different settings is to establish
whether there is an obvious pattern - e.g. is durable performance
especially bad or is synchronous publishing bad whether durable or not
(which might indicate something odd in the network).
Fraser's hunch regarding the type of filesystem and the setting of
--data-dir sounds like a very likely candidate. Though your general
durable performance doesn't look _that_ bad (its comparable with my
laptop) it could be that syncing is slow (e.g. if its an NFS mounted
system?).
