Subject: can you throttle ftp packets?

I'm new to this mailing list so forgive me if this was discussed before.  
But I've been hearing from various sources that it's possible to throttle 
the amount of ftp packets per connection.  I haven't found any info on 
it, so I was hoping I could get some help here.  First let me give you 
some background on what we're trying to accomplish:

	Our ftp site is starting to become very active and our
	response is starting to get sluggish.  At this time we're
	running a Sparc20 with Solaris 2.4 and 256 Meg of RAM.
	So as far as hardware goes we're not even denting the
	maximum capabilities (98% idle cpu with 30+ users).  We
	have a 10BaseT connection to our hub (but could be upped to
	100BaseT if need be).  Our main concern is that if we use
	the 100BaseT interface we'd flood our pipe to the
	internet with ftp packets.  So, I have been hearing from
	various sources that it's possible to throttle the
	ftp packets so that we could use more bandwidth than
	we have now, but still not worry about using ALL of our
	bandwidth.

If anyone has any insight to what I'm trying to do, or if it is even 
possible, let me know.  The help would be greatly appreciated.  Oh yeah, 
we're running wu-ftpd 2.4.  Thanks in advance.

There is this FAQ thingie at http://www.hvu.nl/~koos/wu-ftpd-faq.html
...

But this question is not in it.. yet.

> the amount of ftp packets per connection.

wu-ftpd doesn't support this option (yet?). There is another variant from
the same bsd ftpd, the version used at nic.funet.fi, which has throttling
per user-class.

(It would be nice if their patches and the wu-ftpd patches could be 
integrated in some way...)

You could have a look at nic.funet.fi, the ftpd they use is available there.
