Hello,

Today one of our customer complained that removing clients from application is taking a lot of time around 30-40mins.  So I looked into their database whose DB size is around 340MB and found that our DBA has a called deletion triggers in main table. Triggers will delete all the client information from related tables that 6 tables. Also, I checked the child tables from any additional triggers  but there were none.

Now, when I copied this database to my development environment deletion works fast takes around 5 mins. I also rechecked with their older databases also whose size is around 1GB. Found no slowness during deletion.  

The question arises why this deletion process is taking so much of time at customer environment ?  

Another thing I noticed was that FBServer was consuming 25% CPU usage during deletion.

Thanks in advance.

With Regards,

Joje
