The size of transactions varies, equivalent to 4200 transactions per block. , but the commonly quoted maximum transaction rate is 7 transactions per second Bitcoin. DoS Protection for UDP Based Protocols.

Bitcoin Forum 15 Αυγ 2015 But not increasing the block size may be an even larger threat to the network than low transaction fees. If blocks reach their maximum size, no more transactions can be confirmed until a new block is created, which means excess transactions will be dropped from the network. This scenario may mean higher.
