Bradley, During the summer I had to demo a variety of weakly connected (=write disconnected) and disconnected operations to ARPA. They revealed a variety of bugs in the disconnection code and only through carefully timing my script, I could make things work right. We have just tracked one of the bugs down and will fix it this week. weakly connected operation should be very fast. Lily Mummert and I designed a write back cache scheme for Coda and Lily implemented the first bit; this relies heavily on write disconnected operation and logging and I never seen Coda so fast. The implementation is not complete and the second half is my work -- hopefully some time this academic year. So your observations about performance are consistent with mine and reveal a bug. Sorry, but we are working on it. - Peter - On Tue, 21 Oct 1997, Bradley C.
