On my last order I uploaded the gerbers the 14th. Then on the 16th they were send off for production. They were shipped at the 22’nd and traceable the 23’rd. I also received them by DHL on the 23’rd.
Most of my PCB orders have been like this. One or two days at Seeed before being sent to production. Production for 4-6 days (they only count workdays, not weekends). And one day of DHL delivery (China->Malaysia).
