I've thought about the same thing though. it takes freakin ages sometimes.
no such luck hey, 🙁
was so wishing for this to be fixed in V2.5, it should be instant, sometimes it can take upto 30sec (this only seams to happen when friends have a lot of trophies say over 200) but an average of 10sec is very poor, dont even want to think how long it will take after a year and friends have over a 1000 trophies might take a day to load and use up my monthly MB on 1 profile LOL JKS.
If the 360 can bring up achievement points in a flash on our gamercards so should this, i will give Sony credit as they have been working hard to fix there network and im sure it will become much quicker and cannot complain to much as its a great service thats free.
