ECF service threads [message #624064]

I am trying to troubleshoot some periodic performance problems with Eclipse
3.4. Is there some easy way to prevent all these ECF threads from running?
They are probably just noise but I'd like to disable them and see.

In one thread dump I see what appear to be 3 threads related to JmDNS, 1 to
r_osgi, and 3 for SLP.

I can see that JmDNS is doing an automatic startup. Is there an ECF
equivalent to Window | Preferences | General | Startup and Shutdown to
control this?

No, not currently. We have discussed among ourselves using the
Equinox/OSGi configuration management (org.eclipse.equinox.cm) but it is
not in there yet.

One thing you can/could do is to stop the bundles via the OSGi console.
First start Eclipse with the -console parameter, and you should get a
DOS window with the osgi> console prompt.

Then you can explicitly stop the JmDNS, r_osgi and/or jslp provider
bundles, and these threads should be stopped (if they don't it is a bug
for us and please report).
