Performance issues

Current status

Curently we focus our attention on the first complete implementation of the transmorpher.

Performances

We observe a degradation of the performances with each new version of Xalan. This is why we do not upgrade to newer versions.

The tests we made are consistent across Xalan releases.

A known path of improvement is the use of a multithreaded version of tranmospher that we have abandonned for the moment

Towards incremental computations

The basic utilisation of this version is to produce a set of presentation files from a set of informations files. The future work on the transmorpher must focus on a dynamic version. That is to say,  the transmorpher, will be able, from a set of information file and a set of current presentation file, to compute an update set of presentation files.
To do this, two approach can be used (simultaneously or not) :

An other axe of improvement will be the implementation of more complexe basic process.
And, finally, the last improvment point will be the realisation of a graphical interface to define process.
