I am also running Linux with a demand dial setup. Since I dont't have
a personal proxy yet, I slow down the dialup rate by starting 5 rc5
clients at the same time. My overclocked P166 which runs at 187MHz takes
also about 25 minutes for one block. If I run 5 processes at '-n 20'
they still use only idle cycles and the effect is that they connect
only approximately once every 2 hours. The only problem with this setup
is that it only works if the rc5 clients run almost synchronous. The
Linux kernel's scheduling does a good job here, however, if some but
not all clients do run into 'Connection refused' or other network
related problems, then they run out of sync and they cause undesirable
I try to monitor the execution times via 'top -id10' and use the
Linux 'top' commands 'renice' function to manually synchronize the
processes execution times if they go out of sync.
I am looking forward to put a buffering proxy in place. I'd consider
it an ideal solution if I'd go online only once a week over the weekend
and fetch as many blocks as I can work through in one week. The clients
would communicate with my own proxy on my LAN and the proxy would store
all the results and deliver them when I (or a cron job) sends a special
SIGNAL to it.
