I Have a question on the ps3's minimum requirement internet speed?

[darkprinceofhell]

I have a download speed at 420 something kbps but when i download songs I download at 40 kbps. I think its because the dsl company doesn't let me use full use of my internet speed. Will it have tons of problems loading things or what will happen. I'm getting Little Big Planet and that might have a crowd depending on the server and Killzone 2.
