Hi Mario,
from the APIs you're refering to I assume you're talking about the
EclEmma Eclipse plug-in, right?
Displaying coverage information within Eclipse needs two steps:
1) Requesting a execution data dump from the SUT JVM. This should
typically take a few milliseconds
2) Analyzing the coverage session, which involves traversing all classes
in your workspace depending on the session scope. Depending on the
number of projects/classes in scope this may take up to a minute.
Not sure what time (1 or 2) you're exactly meassuring. But even if you
meassure 1) the analysis might eat a lot CPU as new sessions are
automatically activated. This can be disabled in the EclEmma preferences.
Regards,

Hello together,
currently I am looking for ways to increase the performance of our
Project, if coverage of the junit tests is being collected.
Unfortunately my measurement results show, that we spend nearly all of
the time with requesting dumps.
For example: a suite with 60 Tests performing in 200 ms in an normal
environment, takes 10,5 seconds in an environment, where code coverage
is collected, but 10,25 seconds of that time were spent between:
ICoverage.requestDump
ISessionListener.sessionAdded
see my last
question: https://groups.google.com/forum/#!searchin/jacoco/IsessionListener/jacoco/QBUVXAjS1js/EPck1Y5LYZIJ
Is there a way to increase the performance of the dump?
Best Regards
Mario
