    Is it getting blocked by other queries on production?

    I already thought about that reason but i rule it out as those tables are static (no Insert,Update,Delete).

    Then you may want to revisit it as a possible reason, as deletes get blocked by shared locks, which are what read queries take.

    Let me please make sure i understand you correctly, do you mean that normal select SQLs cause locks which might be the reason for that slow performance?
    If so could i add with (nolock) to all tables used in my SQL.

    Thanks
