Magento / Mysql / Dedivated Server Crashing

We have a current Magento installation and apparently the InnoDB buffer pool / data size is set to the following: 118.0M/1.5G. This is a major recommendation from our web host to change. Here are all of the changes we must make: General recommendations: Run OPTIMIZE TABLE to defragment tables for better performance MySQL started within last 24 hours - recommendations may be inaccurate Enable the slow query log to troubleshoot bad queries Adjust your join queries to always utilize indexes When making adjustments, make tmp_table_size/max_heap_table_size equal Reduce your SELECT DISTINCT queries without LIMIT clauses Variables to adjust: join_buffer_size (> 128.0K, or always use indexes with joins) tmp_table_size (> 64M) max_heap_table_size (> 64M) innodb_buffer_pool_size (>= 1G) If you are familiar with this exact scenario, please bid. We need this project completed right away as the site is live and the server keeps crashing. Only bid if you can do this work right away. Thank you
