Magento Database Optimization - Log Cleaning Script
Has your Magento store been running slower and slower. When was the last time you did a real log cleaning and database optimization. Doing those two things will ensure that your Magento store will stay running smoother for longer.
Log Cleaning to Speed up your Site
The following tables are accessed during normal operation of your Magento store. Some of the logs files are access with every page view, and write/reading to them can dramatically slow down your site when they get large in size.
When I talk about log cleaning I mean truncating the following tables:
- core_cache
- core_cache_option
- core_cache_tag
- core_session
- log_customer
- log_quote
- log_summary
- log_summary_type
- log_url
- log_url_info
- log_visitor
- log_visitor_info
- log_visitor_online
- index_event
- index_process_event
- report_event
- report_viewed_product_index
- report_compared_product_index
- dataflow_batch_export
- dataflow_batch_import
After cleaning out those logs, I have seen a site gain over 5 seconds to their load times.
Optimization/Repairing your Database Tables
I know that Magento uses alot of innodb tables and innodb tables do not use optimization but when your run the command it will recreate + analyze the table. This can help increase your page load times and database access speeds.
Bash Script to Clear Logs and Optimize Magento Tables
The bash script does everything except make a database backup, which I recommend doing anytime you make any changes to your database.
Basic walk-through of what the script will do.
- Put your site into maintenance mode - Important step to prevent database corruption.
- Truncates the above tables
- Repairs any tables that are in need of repair
- Optimize tables/recreate + analyze
- Takes your site out of maintenance mode
Also creates a log file in your home directory, letting you know whats going on in the background
Example of the log file, look for them in your home directory, feel free to delete them but can be used for debugging.
