Alt-Design: Preliminary results FO tree build test

[Peter B. West]

Fop-devs,

Herewith the preliminary results of running the alt.design FO tree build against the 51 page test document supplied by Bertrand. Thanks for the file Bertrand. The file yields a tree of 11044 nodes. The pull buffer is set to 64, the maximum size of the FoXMLEvent pool is 74, and the total number of FoXMLEvent objects created is 78 (next event id -1).

The sytem is a 256Mb PII laptop running Sun's Java 1.4.1 under Redhat 7.3.

Elapsed time from the beginning of org.apache.fop.apps.Fop main to the end of the FO tree build is 15960. The preorder scan of the tree takes that to 16176.

The test is run within a 'time' command with the results
18.02s real 11.71s user 0.24s system

Memory figures after a final GC, besides being somewhat confusing, are

Total memory after GC : 16334848
Free memory after GC : 7242184

The command was:

time java $Fop -fo /home/pbw/public_html/xml/real-life-51-page-document.fo


The full output from the test run follows.
