'Strange' behaviour in KMC

Hi experts,

We run into the following:

When we open a (wpc) webpage in our enterprise portal sometimes the responsetimes are well and sometimes really bad. This fluctuates continously, with no pattern what so ever (if executed twice right after another one can be slow and the other OK).

We have ran a Wily Introscope trace on it and found that whenever the page is slow additional actions are performed:

1. excessive database access on a few tables. It looks like it performs numerous queries which all look the same, e.g.:



All individual SQLs are quite short, but since they are performed so many times this slows down the webpage.

2. SAP Portal|Applications|CM|Repository|Collection|TaxonomyCollection|getChildren

3. Some more actions

These additional actions cause the webpage to be slow and are not peformed when the responstime of the webpage is OK.

Does this ring a bell to anyone?

Can it have something to do with caching? Or content being changed in collaboration rooms?

    We had a similar issue with few selected WPCs which were taking really long (to an extend that our portal server use to crash after few mins)

    It seemed those WPCs were corrupted and we just deleted and created fresh one's. Do check if there are selected wpcs which are causing issues or all of them. If all are causing the wpcs are causing the issue then also check the wpc layout being used if its a custom one.
