It is my understanding that the personal proxy is limited to having
100 keys ready.

Unless DNS doesn't work for you round robin, this should probably be
rc5proxy.distributed.net

I've bumped this up to 20.  This appears to have the affect of waiting
to send blocks to the server until I have 20 in notifyPool as well
as trying to maintain maxkeysready - threshold keys available (ie
80 in my case)

I left mine at 10.  However it appears to be overridden by threshold
as I showed above.

I think this can be any number, it's just that anything over 100
is considered a very large value of 100.  :)  (ie, no more than 100)

Here is a snippet from my logfile showing the threshold stuff I've
observed:

6/4/97 22:04:02--Client at 144.15.40.69 requesting key block.
6/4/97 22:04:08--   readyPool=81   notifyPool=21   uptime=6.0 days   avgrate=2.6
6/4/97 22:04:31--Transmitted 21 keys to server
6/4/97 22:05:01--   readyPool=81   notifyPool=0   uptime=6.0 days   avgrate=2.6
6/4/97 22:11:33--Client at 144.15.40.5 has completed checking a key block.
6/4/97 22:11:33--Client at 144.15.40.5 requesting key block.
6/4/97 22:12:01--   readyPool=80   notifyPool=1   uptime=6.0 days   avgrate=2.6
6/4/97 22:12:02--Welcome to rc5proxy.distributed.net (opus)
6/4/97 22:12:21--Retrieved 20 keys from server

Also, you can have more than maxkeysready currently at your proxy.  In my
case, when I lost my connection I ended up with 138 keys in my notify
pool (and 0 in my ready)
