These queries get executed sequentially which in most cases isn’t a big deal. However, as our database grows in size, response times get longer and longer. A large part of the query time is often just I/O waits. Assuming that each query takes 50ms to finish, these two statements would take 100ms in total. However, if executed in parallel, the I/O waits can be reutilized to perform the next execution.
