Fast is good, super-fast can be problematic with viruses, malware, etc.
I know at least two people who have had major computer crashes with lots of data loss, due to viruses, acquired in the 15 MBps region. Explanation has been that conventional antivirus software isn't fast enough to catch the bad stuff (which certainly makes sense to me).
I also know that some fast, commercial networks use a dedicated computer that does nothing but scan the stuff going in and out.
Good news is that some old, obsolete machines can be fast enough at fairly high speeds, since protection is their only task.
I'm interested in any good info that might be available on more details of this. I can provide one web site but I find some of it pretty cryptic.
