I was going to mention the same thing, but the post implies that this is a recurrent event,
i.e. The shared files are hashed at every launch.
?

Another comment which is very valid is that 10,000 files is way too many in terms of performance... A great deal of bandwidth is going to be consumed in the simple responses to queries, right ?

Far better to establish multiple sharing folders of moderate size and rotate the sharing...

Also, doing a search for the files you are sharing will reveal how many other people are
sharing the exact same file(s)...
If the sources are high for any particular file(s), it is best to remove them from your sharing folders and thereby allow other, possibly more 'rare' files, a higher likelihood of being shared.
