The main limitation of the von Neumann architecture is known as the "von Neumann bottleneck". This is due to the fact that all instructions and all data must pass through the same shared common multiplexed bus to get in or out of the processor, sooner or later things have to wait for other things to get access to this multiplexed bus and the processor gets starved for instructions and/or data. The result is the processor is unable to maintain its designed performance but waits idle instead of doing work.
There is no complete solution to the "von Neumann bottleneck" with the von Neumann architecture, but many things have been tried over the years. The most effective one so far has been the use of independent instruction and data L1 caches. This at least allows blocks of frequently needed instructions and data to be held in 2 separate very high speed memories and made available to the processor on 2 independent busses, so that instructions won't have to wait for data and data won't have to wait for instructions. But even with this, the bottleneck still occurs on the main bus when less frequently needed instructions and/or data must be accessed.

What is the relation between von neumann and Edvac?
The EDVAC (Electronic Discrete Variable Automatic Computer) was one of the earliest electronic computers and is closely associated with John von Neumann, who contributed significantly to its design. Von Neumann proposed a stored-program architecture, which allowed instructions and data to be stored in the computer's memory, enabling more flexible and efficient processing. This architecture became foundational for modern computing, influencing the design of future computers beyond the EDVAC. Thus, von Neumann's concepts helped shape the evolution of computer architecture.
