It seems i had setup a Pizza Count for each customer, this was making the order placing slow, after removing overall POS is working well, only loop functions are slow. Nowadays, 15 to 20 tickets are looped together. I am trying to re setup the whole delivery after removing all actions rules, widgets, etc.
I noticed that the tutorial do not contain the screen for “Store Selected Deliverer”, I maybe using the wrong tutorial, let me know.
I have identified the problem which was making SambaPOS slow. I asked an IT engineer to check the server, and he showed that the database tables has been fragmented. after defragmenting the main tables like, Tickets, Ticket Entities, Entities SambaPOS is working really well.
Therefore it is best to regularly defrag the main tables in the database.
Hope this may be of help to anyone.
