A revised discussion of ISIS V3.0 performance can be found in pub/isis-perf.ps.Z on our anonymous FTP repository ftp.cs.cornell.edu Log in as anonymous, password your email address. Say "binary" and then transfer this file using the command "get". Uncompress it and it can be printed on a post-script compatible laser printer. Summary: in most cases, our performance is now quite good. For example, we can send several hundred small asynchronous cbcast's per second to a small group, our point-to-point data transfer rates equal or exceed TCP rates, and our RPC time is down to 6.6ms (cbcast to one remote destination who replies; null packets). All this for Sun Sparc 1 workstations and a 10mBit ethernet. One comment: ISIS is not a simple system and we were constantly fighting with packet loss in UNIX. So, if the measured curves aren't uniformly smooth, this is really not very surprising. This figures are all more recent then the ones in the TR version of our paper on Lightweight Process Groups and Group Multicast. -- Kenneth P.
