thats done by your load time, which is done by your ram, the more ram you have the faster your load times, the less ram the slower your load times
i have had experience with all load times, i have used computers with 256mb, 338mb, 512mb, and 1024mb
so if you cheap out on your ram then you will always be last, and you cant have a random join thing because that would be bullshit and piss off people who payed a lot of money to have lots of ram to have shorter load times
