NetBackup 8.1 - Performance issue (during upgrade but also after)

At this moment the note is not public so here is a little preview.

I have seen performance issues when I tested NetBackup 8.1 under lab and I will detail them later.

Now, back to the article.

Well, I will tell you the cause, it's all those "senior bat experts" working at Veritas.

Recommendation would be to upgrade everything to 8.1 but since there are performance issue why I would upgrade ? Leaving clients on 8.0 will also create issue with restores.

It was not enough that the "focus on security" has created millions of issues with these client certificates ....

There are also performance issues after the upgrade not only during.
