https://en.bitcoin.it/wiki/Scalability#Scalability_targets https://en.bitcoin.it/wiki/Scalability#Scalability_targets > Today the Bitcoin network is restricted to a sustained rate of 7 tps due to the bitcoin protocol restricting block sizes to 1MB. I've heard the number from other sources as being 6 or 7 before too, particularly after the scale tests I believe. I know there's the blocksize increase debate which will make this comment inaccurate soon. Also, I believe that a 0 fee transaction will still get processed eventually and, since such a thing is valid, it's not going to stop spam entirely, just slow it a lot.
