Cool. Will look at it. Thanks for your help James.

Hi Laurent,
I think at this point it's safe to say the problem is solved. If you
wanted to check it out for yourself, Christian committed the spiffy
new ID generators here:
https://hl7api.svn.sourceforge.net/svnroot/hl7api/trunk/hapi-mvn/hapi-base/src/main/java/ca/uhn/hl7v2/util/idgenerator/
. FileBasedHiLoGenerator is the default, and it is effectively doing a
batch-cache as you suggest.
The next version will probably be numbered 2.1, but it is certainly at
least a few months away. A number of under-the-hood cleanups have been
made, and they will require a fair bit of testing before we trust them
enough to release them publicly. Naturally, you can always build from
source if you wanted to check it out early.
Cheers,
James

This is good to know. By "next release", do you mean 3.0, or a
2.1? When do you think that would be?
I have had similar issues on a project many years ago. The
solution we found which worked well in practice was to batch-cache
IDs. I am not sure how the IDs for the ACKs are generated though
so this may not apply.
If the problem has been solved (and soon to be in the code), then
great. Otherwise, i would love to have a discussion with whomever
to see if this would work well.

Hi Laurent,
The main reason for this is that this method assigns a new
sequential ID to each ACK message it generates, and it uses a
file to keep track of that sequence. That file is read and
written on each message, so it is a bit slower than you might think.
The next release of HAPI has a great new implementation of this,
oddly enough. Christian Ohr has written a pluggable ID generator
module, which can use "hi-lo" files which are only occasionally
read, as well as memory only and GUID type implementations which
are faster still. Unfortunately that release is not yet out, and
probably won't be for at least a few months.
Cheers,
James

Is there a reason why creating an ACK is so slow? I am calling
DefaultApplication.makeACK(_Msh);
This takes almost as long as the parsing of the full message
coming in which seems counter intuitive.
I am on V1.2.
