We have a problem with creating shipments in magento.
It's taking over a minute to create a shipment and e-mail the customer.
The problem started two weeks ago, and I have checked the logs and opened the firebug console during shipment creation. They all show no errors, only that it indeed takes about a minute to create the shipment (around 67 seconds).
Invoices can be created without a problem. Invoices with a tracking number are also taking a long time ofcourse.
We also emptied most of the abandoned carts, because it was the biggest log in the database. The other known big logs are being cleaned every night.
One extension that uses the shipment creation has been turned off, but unfortunately that didn't work.
Any idea what we could try next? Is there a tracking number log in Mysql we should empty?
We are using magento 1.8.0 and only flatrate shipping options (nothing with an API).
