PLEASE ensure that you are using a brclient of at least 0.14 ("grep comment.inffo brclient" to discover what you are using) You can updare brclient while brloop is running. Some people are still running old versions, and this is hammering the server.
It also helps to run at least brloop 0.05 ("grep BRLOOPCOMMENT brloop"). Unfortunately the web page under "Socket based key doler" points at brclient 0.13 and brloop 0.04. Could you fix this please:)
I had a similar report before, and it turned out to be an over zealous WWW "cache" :-(( HOWEVER: there is now a new brclient 0.17 which should go faster that pre 0.16 over "slow" links, but shoudl also work over "fast" links (which 0.16 sometimes did not). SO: all 0.16 users should upgrade, just in case the link goes fast!
