Hi

I have a problem with an application. It is not in production yet so very few users. The problem only occur sometimes. Most times if you havent touched anything for a while. It is not our portlets generally speaking. I it for example when uploading files. creating web content and so on. Can you give me a hint we to start? Do you have any tools for this.

I use the tomcat bundled version.

Thank you as usual david. You mean on my local liferay portal?

I installed VisualVM and it looks like nothing strange as I can see. Maybe a network problem.

Is the snapshot taken during the slow period, or are you saying it is consistently slow?

If you are having performance issue while uploading file or creating web content (do you mean when saving web content?), it may be an issue with network or your database.

Check if performance slows down while other is uploading a file or if it's just slow to upload your file.

Thank you. I have to investigate this further beacuse the slow periods is very rare and did not happend to me during the 30+min I was clicking around. The snapshot is not during a slow period.

This is how our customer describes it.

"When it comes to performance, I have sometimes experienced this when I go between pages or open an editor such as when I am editing an article."

The editor performance is probably javascript download time as it oftens happens here on liferay.com
OR
it just may be that your customer is running something else while viewing or editing a page.
