With default parameters,

max_clients_per_second * min_reask_delay = 5 * 720 = 3600

30 * 250 = 7500

So potentially you have too many files downloading, but if half of them are
rare, it's possible that you're closer to the limit than that.

More bandwidth (both of downlink and uplink) will be used to connect to
peers instead of uploading or downloading, so you'll lose some efficiency.
In a recent post, mldonkey evaluated the "cost" of connecting to a peer to
between 300 and 400 bytes per connection.
If you have an asymetric link, it will be more noticeable on uploads, your
uplink will be used just as much, but the rate of file data uploaded per
second may decrease. That can be measured with client_stats output.

It should automatically lower max_sources_per_file, so popular files will be
more affected that rare files, just like if you lowered max_sources_per_file
by hand...
