Thanks for the suggestion, Philippe. Here's the output: ** debianoak:/home/nbp# hdparm -tT /dev/hda /dev/hda: Timing cached reads: 1192 MB in 2.00 seconds = 595.20 MB/sec Timing buffered disk reads: 6 MB in 3.24 seconds = 1.85 MB/sec ** That looks reasonable to me - very fast from the cache and a lot slower when it has to be buffered (on the hard drive, presumably). But, what do I know!? Following up Listrcv's suggestion I had a good look in /var/logs/syslog and it looks as if it may be something to do with gconf2 being upgraded.

There seems to be a repeating pattern of resolving an address to do with gconfd first for user root and then user nbp - and making a real meal of it. Any ideas anyone? I'm going to try and find out more about what gconf does.
