Annoyingly its the slowest single core pile of rubbish in the office, Its just got loads of Hard Disk space..... (1Gb of Memory, Duron 1200) but then most of my machines are not much better, some are actually worse, I even have one that running on hmm Pentium 3, 800MHz and that's my hmm remote access machine.....) I was speculating at restarting with, --fast-read-xml and -wpd But I think I might be better starting with a clean sheet of paper, I only really wanted to know what I was up against. Peter Peter.
