UBB.Developers Forums UBB.threads 7 Development How Do I? Best way to integrate user table

For sure your board is busy - no doubt about that - due to the page views you quoted.

I believe that you won't have a problem with the common use of the w3t_Users table from both applications

The best way to go about this is to create a test integration and ask from some of your most "trusted" users to become beta testers, testing the integration of application A while being in the forum at the same time. Once you get a feel as to what the load increase will be then you can forecast the expected loads when all users are integrated in this modification.

Some things to help monitoring will be the load on MySQL, which should be tweaked appropriately to cater for the additional load on the .threads database and it wouldn't hurt monitoring the resources that apache uses this test period. These statistics will give you the adequate information to see how you will proceed with this.
