[Zope] XML Sooooo Slow

Hi, Just had a play with ParseXML-1.0 on Zope 2.3 on 433 Mhz Celeron portable. Edit the XML file is so slow. <?xml version="1.0" ?> <Jobs> <Job id="1">Text here</Job> <Job id="2">PNC want 10000 faxes on tuesday</Job> <Job id="3">Fisrt Choice Water Coolers</Job> </Jobs> Zope seems to run fine - just XML editing? Is this normal - clicking on the Job id='2' #text field takes approx 18 Seconds to get to the management screen. Anyone have any suggestions? Thanks Dave
