CJdropshipping - Priority Processing experience?

[mcgifts3]

Hello, i use CJdropshipping for custom jewellery currently... 

overall the processing and shipping experience has been absolutely horrendous, like x2-x3 from what it says. 

i've got 3 orders still pending, not even processing, from multiple weeks back

i've bought other products in the past that had the same result, but nothing in quantity to where i could have an opinion... until now

Question is, how much quicker is the processing once you've earned priority processing?

(£2,000 in orders i believe) - like if something would normally take 3 weeks to process, would it cut it down to a week or under as advertised for %95 of orders? or is it marginal improvements
