Re: guru needed - large configuration MySQL-Max InnoDB - 4.0.16
You don't mention CPU type but do mention RedHat 9. Is this on 32-bit x86 hardware or something 64-bit? How do you set innodb_buffer_pool_size to anything 2GB on a 32-bit box if it is? I've got it set to 7GB on a dual Opteron box with 8GB RAM with great results so far (in testing, go live next week probably). Hi, innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend innodb_buffer_pool_size = 6G it looks like your InnoDB tablespace is less than 2G. If it is true then IMHO it doesn't make any sense to allocate 6G for innodb_buffer_pool. InnoDB won't use it.

I'd up your buffer sizes - the mysql manual has some clues as to setting these values? You might want to increase the query cache size. I'd then run it and watch the stats.
