Hi list,
I have a question rg. performance of the ServiceClient compared to the
OperationClient interface.
Personally, I would expect the performance* to be roughly the same for
both interfaces since ServiceClient is just a more convenient wrapper
for simple tasks.
But now I have measured the invocation times (as defined below), and
found that my "handwritten" client (which uses ServiceClient and AXIOM)
takes about 4 times as long as the stubs generated by wsdl2java (which
use the OperationClient interface) to produce a result against the same
service. I guess the reason for this performance boost of the client is
either that (a) the OperationClient interface is for some reason a lot
faster than the ServiceClient interface or that (b) there is some tricky
optimization going on somewhere in the ADB stubs that I failed to see so
far.
Has anybody any insight here that could help me to improve my
self-produced client, or any other information that would help me
understand the differences here?
thanks in advance,
philipp
P.S.: I also did a few comparisons with other frameworks (WSIF and
XFire), and Axis2 seems to be doing quite well so far. Definitely
quicker than WSIF, and in a good tie with XFire (but I still have to do
a lot to get really conclusive results here).
*in this context I mean with performance the time between calling eg.
ServiceClient.sendReceive() and the response being returned to the client.
