We're running quite an extensive setup with dozens of projects and thousands of
builds for each project. At the moment we're purging build artefacts but keep
the actual build history+metadata indefinitely. Maybe because of that, startup
up hudson now takes in excess of 40 minutes. vmstat shows the disk being busy.
It would be preferable if startup time of hudson were unaffected by the number
of builds or projects. I'm putting this as "enhancement", but it's really a
rather important one for us.
