How much memory do I need to load a 50GB+ MySQL table?

http://serverfault.com – I've got a MySQL table with a .MYD file of 44GB, and a .MYI file of 34GB. I'm running scripts from the command line that analyze the data in this table. MySQL is not maxing out the CPU, my memory IS maxed, and VMSTAT is reporting that data is being swapped to disk ... but I'm not terribly familiar with this utility and it's reports. I am running a High Memory Double XL Amazon EC2 Instance. It has 34GB of RAM. I am not very familiar with MySQL tuning and the system is running with the default install on Linux CentOS. Does the current machine have enough memory to deal with this table effi (HowTos)
