LKBEN11492: What is lock escalation on sql server
Symptom
Your queries are slow, your server does not have a high cpu and there is still plenty of memory
Cause
This might be lock escalation
Solution
Sql server need locks to do it's work, thats normal. When a single transaction is changing more than 5000 rows, sql server will not do row locking but will exclusively lock the whole table. During this time, no other operations will be handled until the transaction has been committed or rolled back.
