I have updated to the last beta version of ConTeXt MKIV. It's very
good, reduction
in memory usage is huge. Now it's just about 100MB with the same test.

mkiv lua stats : fonts load time - 5.703 seconds

mkiv lua stats : luatex banner - this is luatex, version
beta-0.50.0-2009122422

mkiv lua stats : control sequences - 29965 of 165536

mkiv lua stats : current memory usage - 98 MB (ctx: 100 MB)

mkiv lua stats : runtime - 7.891 seconds, 0 processed pages, 1 shipped
pages, 0.127 pages/second

SyncTeX written on test.synctex.gzMTXrun | total runtime: 7.967

Best wishes,
