comment Why does a wired network slow down with user increase?
Your results are unusual. It's hard for us to speculate what accounts for them without even being able to see them, without knowing what network technologies were involved (what kind of switch? GigE? Fast Ethernet?), or having any clue what CPUs and operating systems were involved. But it makes sense that the last test would be faster, it wasn't limited by the bandwidth of a single link.

Pretty much every switch is like that. Otherwise, if you made a configuration change that locked you out, how would you get back in?

Instead of accessing the switch from a browser, access it using ssh.

It sounds like something specific to the way you tested or the environment you tested in. Was this TCP or UDP? How did the transmitters pace themselves?

comment RSA keys - virtual hosts
There's nothing wrong with using the same RSA key pair for every account if the same human being has access to them. And there's nothing wrong with using multiple RSA key pairs for an account if more than one person has access to them. RSA key pairs should be owned by agents, such as users. And an RSA key pair allowing access to an account gives that agent access to that account.

comment Server hard disk read speed and client download speed, is there a connection?
It depends on the implementation of the server. It might well be designed to hold specific, selected objects in memory. Or it might not.

comment Network Balancer for LAN?
Note that QoS on your local router generally won't help when it's download speed you care about. Your local router doesn't get to choose which packets your ISP puts on the wire to you, only which packets it puts on the wire to your ISP.

The message about the mismatched host entry should have told you which entry was in conflict.

comment Debian virtual memory reaching limit
Is this a virtual machine? There seems to be fairly high swap usage with nothing obvious accounting for it. Check for a tmpfs filesystem with lots of stuff in it, like perhaps /tmp or /dev/shm. A tmpfs filesystem is backed by swap. If you have lots of junk in one, it will consume swap but not be attributable to any process.

comment Debian virtual memory reaching limit
It would help if you described the problem. What is slow exactly? Was it always slow? Did it suddenly get slow? Is it always slow? Your stats show an idle system, hard to imagine how that reflects a slow system. Can you post the output of standard tools like top or free. For example, I have no idea what this tool considers to be "used". I'm also pretty baffled what unused virtual memory would be. If it isn't used, then in what sense does it exist?

comment Debian virtual memory reaching limit
Freeing up memory would make it slower. If it's running slow because it isn't using enough memory for its load, forcing it to operate with even less used memory would just make it slower!

comment windows 2008 r2 internet sharing via network bridge
Can you assign PC B an IP address inside the 192.168.1.xxx LAN? If so, just bridge the two network interfaces on PC A.

comment Use ntpd to log time adjustments rather than set system clock
It's not clear what you are trying to do. What would reset or adjust the time exactly?
