Many downloads in queue -> zero transfer?

Hi!

It seems to me that if I queue more and more files for download the number of downloads that actually start rapidly drops. Like if there are 4 files queued one or two of them may eventually start downloading, but if there are sort of 100 files in the d\l queue, nothing happened for hours yet. (status is "waiting" on approx. 95 and "connection failed" or similar on the remaining 5).

Is this a general gnutellanet effect or a client - specific problem?

Either way, I'd like to keep the files somehow in the queue so I won't have to keep re - searching all the time. Like queue files and leave phex to get them.

Would boosting the "parrallel downloads" to something beyond infinity help? I suppose that would bring the machine down to a crawl, resulting in no downloads again?
