Advantage:increasing sort area size decreases the I/O, hence quicker sorting process.
Disadvantage: increasing sort area causes sort process to allocate more memory, which effects the OS memory allocation resulting in paging and swapping.
large sort area sizes can used if you are using with a minimal sort_area_retained_size parameter.

we had a customer of the sort_area_size=10000000 in their database, the temp table space is 256MB, the db_block_size is 8k. They have some performance problem, I think it's probably related to the setting of sort_area_size(we have only one user). So what's the benefits/disadvantage of too big sort_area_size?

Thanks,

Chris
