Hi Tom,
Is it going to get the profile data that I have seen before?
In that case, we only get partial data. For instance, we will only get
the time for WebContainer.postConstruct() without knowing the details
within the method. Per our discussion, we can "adjust" the timing to
check whether we can see anything there. But this is not deterministic.
Is there a tool we can use to profile all the data?
Please let me know.
Thanks.
