Remote Services Performance issue ? [message #760522]

I have installed ECF 3.5.3 SDK in my Indigo SR1 target platform to test ECF Remote Services.
Hence, I have imported hello examples from ECF 3.5.3 sdk and that runs.

Nevertheless, with standard remote services or DS hello services, the HelloClient code takes a lot of time (15 / 20s) to bind to the remote service Hello (made available by the server).
I tried different discovery protocols : (zeroconf, generic) or (zeroconf,rosgi) but it does not change anything about the time to bind to the remote service.

Hello client and Hello host are running on the same workstation (Windows XP). The remote service is hosted on the localhost. I did not change anything in provided examples.

Does anyone have an idea about this issue ?

Do I understand this correctly. It's not the performance of an
invocation of a remote service, but the performance of discovery to find
a service?

Hi Markus,
You are right. I ran others tests with zookeeper discovery protocol and the issue is solved. Hence, it is linked to zeroconf protocol configuration.
Do you have an idea where I can find more details about the different discovery protocols configuration ?

Stephane.

Hi Stephane,

zeroconf/mdns, like e.g. DNS-SD or SLP are standard-based protocols. You
find the corresponding specification on the web.

ECF discovery just wraps various standards and provides a generic API.
