Pretty poor unless you have the doffs needed to either spread it or make it take systems offline after it's finished it's first set of offline.
The reason being that anything where it lasts long enough to see a benefit is usually so weak you could have gone for more offensive skills to take it down quicker. Anything where it might have been useful (say tactical cube) they are insanely resistant to it to the point where it lasts a few seconds and you won't notice any difference. Even with pricey doffs it's not much better.
PvP it's much better if only for how annoying it can be if fully specced into.

It is through repetition that we learn our weakness.
A master with a stone is better than a novice with a sword.
Has damage got out of control?
This is the last thing I will post.
