- The V3.0.7 patch release we have mentioned is now available for those
- who need it. It will be sent out automatically for new Isis orders
- (including academic ones) but if you already have V3.0.7 it won't be
- sent to you unless you request it.
-
- This patch is exactly the same as V3.0.7 but with some minor problems
- corrected, all of which turned up after V3.0.7 went out:
- - Slow performance with overlapped groups using the "x" option
- - Slow performance on some platforms that disable TCP_NODELAY by default
- on creation of TCP connections.
- - Tendency to hang when extremely rapid sequences of pg_leave/pg_join
- or pg_delete/pg_join are done.
- - Performance problems seen with the spooler because of
- * it not using bypass communication, and
- * lack of appropriate flow-control mechanisms
- These matter mostly to people doing wide-area communication directly
- over the wide-area subsystem or through the WAN news interfaces
-
- V3.0.8 will be a genuinely new release, and when it comes out there will
- be a substantial performance improvement in the WAN mechanisms and spooler,
- as well as heavy use of IP multicast (when available from the vendor) all
- through ISIS, and the ability to connect to ISIS from a Macintosh on Mac OS,
- from a PC, and perhaps from NT. Availability of V3.0.8 is planned for
- very early in 1993 -- mid to late January.
-
- Email to sla@isis.com if you need to get the V3.0.7 patch release and
- are not sure that it will be sent out to you automatically.
