<div>at the moment we do not have hierarchical groups, but we
thought about it.</div>
<div>So having a flat group structure, I was even more surprised
about the time it takes.</div>

</div>
<div>So for the moment we are using getGroupIDs(false), this is

<div>My mail was rather to make you aware of it, in case you were

it has a TODO stating the implementation should be replaced, but it
doesn't say why and maybe the implementation was changed already
because it seems to have a version2 and hence the TODO should be
rather deleted.<br>
<br>
I am happy to have a closer look at it, but it would help me if you
could provide me with sample data to reproduce the performance
issues which you are experiencing.<br>
<br>
Thanks<br>

<div>I observed a severe performance issue if you call
the getGroupIDs method with boolean TRUE (return
also parent groups):</div>
<div>- I have 1000 users locally installed</div>

<br>
</div>
you mean the peformance issue?<br>
<br>
I think this depends very much about the context, how the
groups are being nested and how often one is calling this
method.<br>
<br>
In what context are you using it or rather what do you try
to accomplish?
<div class="im"><br>

<div>However: the difference from a performance point
of view seems a bit too distinct, maybe the code
could be improved? </div>
<div>If there is a description somewhere, what
exactly YarepUser.getGroupIDs(true) should do,</div>

See the javadoc at<br>
<br>
src/core/java/org/wyona/security/core/api/User.java#getGroupIDs(boolean)<br>
<br>
You might also have a look at<br>
<br>
src/util/java/org/wyona/security/util/GroupUtil.java#getGroupIDs(Group,
boolean)<br>
