Well, not sure if this is really a bug, but here I go anyways.

With /hmake, you can specify the size of your hashtable. The manual claims that, depending on the number of items stored, the larger the size, the faster it will work.

Now, my bot stores quite a lot of (seen) data in a hashtable:

Code:
14:16:37 ~ | Knoeki^DSS      > !eval msg # $hget(seen, 0).item
14:16:37 & | Miffy           > 23705


23705 items as we speak. Now, this is all fine, since it works, but... why isn't it possible to create hash table with a size of over 10000 items, even though you can store unlimited items in it? Why a limit on the inital size if you can practically store an 'inifinte' amount of data in it anyways?
