@ZettaSuro A single method call instead of a loop every time. Set up the stream once to write to all the streams you want, then just teeos.write(stuff).

source: @override public synchronized void write(final int b) throws IOException { super.write(b); this.branch.write(b); }

I'd bet quite a bit that if I look at the Apache TeeOutputStream source, it does them in series like this, not in parallel in separate threads.

It does write all the streams in one method call, which is the problem at hand. | |
| Feb 24, 2013 at 17:13 | comment | added | rurouniwallace | @Kevin No thanks. A for-each loop does not solve the problem of how to write them simultaneously. A for-each will write to the streams in sequence, they won't be written in parallel (i.e. simultaneously). | |
