can you send this to me for testing?<br>

<div>Then you just need a resource which calls the method with
Boolean.TRUE, you'll see that it takes some seconds even without

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>

<div>I observed a severe performance

yes

<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><br>

<div><br>
</div>
<div>2)</div>
<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>
