Re: Problem: INSERT DELAYED works like normal INSERT

What value do you have for key_buffer_size? If it is the default, that is much too small for efficient use. Change it to be about 20% of _available_ RAM.

How many rows are you batching in each INSERT? If you are inserting rows one at a time, something else is going on to cause "users are blocked few seconds". Let's see SHOW PROCESSLIST during one of these incidents.

Can you change to InnoDB, which uses "row level locking" instead of "table level locking"?
