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,

what's about char[] array/string reusing?
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 patched jasper to use char arrays instead of strings, and it gaves a
good performance improvment. It's not perfect, but is works.

Resin is also concatenating the strings, to reduce the amount of write
calls. In this particular test, it is useful; IRL, probably a bit
This seems easy enough to implement, so I'll look into it. Concatenating
texts is also on my list, and it should help a little in this case.

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

I took a look at o.a.j.runtime.JspWriterImpl
two
methods should be on par in terms of performance. That is, I don't see
any extra unnecessary copies.
Perhasp the culprit is those extra writes?
