Currently I have on program that does the lookup. Will this be faster?

Sure.  Think of data queues as messengers.  On the one end you have a client
who needs to know the on hand quantity.  So he puts a message on the queue
with the part number.  Then you have a server program you wrote who is
listening to that queue.  When he hears the message, he does the lookup and
returns the quantity by putting a message on another queue (or the same
one.)  You can make the queues 'keyed' so that the two ends of the
transaction share a common ID number.

client: send ID 541, part ABC
server: recv ID 541, part ABC
        look up ABC
        send ID 541, part ABC, qty 34
client: recv ID 541, part ABC, qty 34
