Yes, the code is better (IMO) and performs a little better also.
However, looking more at my profiler, I think the problem with that
benchmark is all the not optimized int -> String conversions. Since
that's not too useful in the real world (but in that benchmark,

Create only a char array for each unique templatetext node.
->
10 x char[] jspx_text_1 = "something\n";
1 x char[] jspx_text_1 = "something\n";
Won't the VM do that internally ?
Since apparently you have examined that issue in

I have implemented generating text strings as char arrays, with a
compiler option to turn it on and off, and did some timings on the
benchmark. Just as I suspected, the benchmark did not show much
performance difference, when the option was turned on and then off.

That would be awesome.
The test had a *lot* of writes, so this would save hundreds of write
invocations (as well as making them faster

Resin is also concatenating the strings, to reduce the amount of write
