Similarly, Unless you sort the list of versions by location on the disk the runtime can be quite slow indeed. 'apt-cache dumpavail' is about what you are doing and you can measure how fast it runs vs what you are up to. That fact that you are seeing 1s on a modern box vs 30 mins reported suggests it is thrashing the disk cache. Jason
