I am considering upgrading network components for better throughput performance. I have 2 networks with 3com 4500G 24 Port Gig switches acting as the backbone. These were purchased and installed in 2005. I assume these were designed with older networking technology. Would there be any overall, significant performance benefit in replacing these switches with a newer switch such as the ProCurve 2810G or something similar? I only need layer 2 switching. Are there benefits in the newer switches, such as newer designs or technologies that increase handling of network traffic leading to significant increase in performance?
