I periodically do contract work for an educational company that uses reclaim. In this case the contract was for dedicated hardware to which the edu company has whm and cpanel access. Since you're specifically concerned about the network side of things, I'd recommend to start logging the bytes transferred out from your current system, if you aren't already doing so. You could then ask your institution about what underlying infrastructure is being provided by reclaim. That will hugely impact performance. They offer lots of flexibility in terms of what infrastructure is powering your cpanel-based services. Ultimately, the educational company decided to move its heaviest-usage production infrastructure off to aws because of inconsistent performance as more services were added to the hosting account and some services scaled up. The whole point of cpanel is to allow users to spin up arbitrary services without technical barriers, which can make it very difficult to offer predictability in the shared environment. They still have their lightweight public/sales sites and their sandbox systems with reclaim and have been quite happy with that.
