Thanks Evan for helping Daniel. In theory it ought to be possible to have a nearly unlimited number of downloads in the queue: That is precisely why we decided to use a database to store the progress of downloads. Unfortunately, in practice, disks are slow, and the more stuff is queued, the less of it will be cached in RAM i.e. the more reliant we are on slow disks. There are many options for optimising the code so that it uses the disk less. But unfortunately they are all a significant amount of work. See https://bugs.freenetproject.org/view.php?id=4031 and the bugs it is marked as related to. > On Mon, Mar 8, 2010 at 8:05 AM, Daniel Stork <stork...@yahoo.com> wrote: > > Defragmenting the database did help.
