Yes of course you can and...you should As the my.cnf says # InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and # row data. The bigger you set this the less disk I/O is needed to # access data in tables. On a dedicated database server you may set this # parameter up to 80% of the machine physical memory size. Do not set it # too large, though, because competition of the physical memory may # cause paging in the operating system. Note that on 32bit systems you # might be limited to 2-3.5G of user level memory per process, so do not # set it too high.
So if you are using innodb as you main engine i suggest the advice of 80% of ram, obviously it depends of the current load in the server; if you are running ie. an application server you would have to divide the ram according to each needs. Carlos. On 8/15/06, Shaun Adams <[EMAIL PROTECTED]> wrote:
I'm currently running RHEL4.1 64-bit, mysql 4.0.26 w/ 4GB RAM and have my innodb_buffer_pool_size set to 2GB, My question is, can I increase my ram to 8GB and set innodb_buffer_pool_size to 4GB or even 6? Thanks
