Hi, I agree that this question should be best asked at the Batik mailinglist.
If it takes 20 secs to update 100 text elements then there is something seriously wrong in your application. Either you are running at the memory limit (per default Java apps only get 64MB of memory) or there is something else in your code that is slowing down the application. In my experience updating 100 text elements usually happens in <1 second if you do it correctly. If you update the same text elements again and again I would also consider to cache references to those elements and not use getElementById().getFirstChild() again and again. But please post your example on the Batik mailinglist. I am sure they are able to help.
