I'm developing a WP multi-site network which have a goal of 10,000 sub blogs. The site needs to store custom data related to the user. There are additional 20 fields of data for each user. What is the best way to store data in the WP?
- Store in a custom table
- Store in user meta table
I'm using a dedicated server for the database. The specs are 16GB RAM - Intel(R) Xeon(R) CPU X3430 @ 2.40GHz
Store data in the User Meta table will affect to my site's performance?
