One day you start receiving complaints that your beautiful 4D application is experiencing slowdowns. This happens at random times through the day and you can’t reproduce it in-house. It all worked well before and you do not know where the problem is. Is it a new method you just added or is it more users than usual? Maybe one of the users doing something completely unexpected?

I will show you various ways to troubleshoot the slowdowns based on our decade of experience of scaling up and troubleshooting 4D Enterprise servers from small single-school applications to large district-sized 4D installations. In a matter of few minutes, you will learn our full collection of tips & tricks that took us months of toil to discover.
