Good day!
First, it is necessary to optimize the database, fix the queries, and then think about Redis....
I have been working with OpenCart for 14 years. I know all its weaknesses and can fix them.
Ready to help:
- Cache similar data (manufacturers, categories, etc.) in Redis to significantly reduce database load.
- Optimize SQL queries and add indexes to eliminate slow JOIN/GROUP BY.
- Ready caching modules (Jet-Cache, Page Cache, etc.) will speed up implementation, but without query optimization, the backend will still load slowly during periodic cache misses.
