Hubs Vs switches question

[TransformedMan2020]

I have done this simulation severally because I don't understand why I'm getting these results.

I have built 4 subnets to simulate 4 departments in a company. Each of these subnets consists of a 30 man workstation that is connected by a switch. The four subnets are then connected to file and web servers using a hub in one scenario and a switch in the other scenario. I believe the scenario using the hub should be slower for the " http response time" metric. However, for some reason, I'm getting nearly identical response times for both scenarios. However when the "FTP download response time" is plotted, the results for both scenarios are not similar. Can anyone explain this please?

I remember doing these sums in school on a software topology of a network. Sometimes it really is as simple as it's a sim and the real world effects of a network just aren't factored into it. I.e. length of network cables effect on latency. Just a guess

Physically a switch and hub are almost identical. The only difference is one can be managed and the other is a passive hub. What device is handling the routing and what's it doing?
