Optimization of Innodb tables

[Kevin Tyson]

My Database is almost exclusively INNODB tables, we run optimization of out database once each month. My understanding is that optimization is achieved by copying to a temp table, truncating the table and rebuilding/reindexing the table (please confirm if that is incorrect). A colleague of mine indicated that we could get better performance by adjusting our INNODB buffer pool size prior to optimzation. I don't see the benefit in doing this since optimization is done on a per table basis (although we run 4 in parallel through a shell script). Can anyone advise on the affect of the innodb buffer size specifically on optimization?

Thanks in advance,
Kevin
