It may a reasonable effect if: 1) you are already saturating the link 2) you have sufficient number of partners and they you doing large block transfers If you have a single machine just talking to one other machine, LACP will not help by definition. You likely need a faster link. Given the above, LACP can help if you tune your stack and your apps know how to leverage the tuning. I have spent a number of years working in search and lacp has been run of the mil. Typically I would see 1.2 Gb/s from boxes whose job it was to forward search indexes to searchers even, if in some cases, going over a router. This of course was on an optimized stack. I seem to recall Hadoop clusters going has high as 1.4Gb/s in our environment. LACP is good for link redundancy on servers connected to virtualized chassis. I use this instead of IPMP. LACP is even better for distributing load on switches, which was the original intent of etherchannel from which LACP rose. j. _______________________________________________ OpenIndiana-discuss mailing list [email protected] http://openindiana.org/mailman/listinfo/openindiana-discuss
