problem with setting the speedlimit

[neoxed]

There's an entry in ioFTPD's knowledge base which explains the differences.

Q: What's the difference between the registered and unregistered version ?
A: At the moment, unregistered version has the following limitations:
- SSL is not supported
- Per client speed limits are not included
- Ordinary memory managment
- Limited to one io thread per process
- Smart disk-access queue is disabled
