comment sql server use of memory
The clue that you need more memory is excessive disk I/O. You can't really tell from memory utilization because that will only tell you if it is using the memory, not whether it needs to use the memory.

comment When does a browser send HTTP payload separately from the HTTP request?
It's random and unpredictable. Because nothing is supposed to care, no special effort is made to make it one way or the other way. (It can depend on how the client is coded, whether the client gets to keep the CPU while it's processing the entire request, whether a proxy is used, the MTU of the smallest link on the path, whether active bandwidth management devices are being used, and who knows what else.) It's not that the software "sucks", it's simply not an HTTP server, and so it cannot be accessed with an HTTP client.

comment In Wireless Networks, What is IV?
It's sent in the clear over the wire, but it does encrypt because it is part of the key. The point is to encrypt each packet with a different key.

comment Ways to estimate which network destination result is shorter/faster network path?
If you definition of "faster" is the time it takes to reply to a custom database request, then time that. That's how you'll know which one is faster. (If you have cooperation with the other end, ask them how to tell. Perhaps they'll even offer you a specific query for that purpose.)

comment Why Place Load-Balancer Behind Firewall?
The web servers are only on the internal network if they're behind a firewall. That's kind of the definition of "internal network". If a device is connected to a load balancer that is connected to the Internet, it's not on an internal network unless the load balancer is also a firewall. (If the load balancer is also a firewall, then it's kind of redundant. Though some people prefer to control everything from one firewall.)

comment Providing internet redundancy for our colocation provider
I would hope the two ports they'd be giving him would be off different switches. Otherwise, it seems they should be able to provide the same level of redundancy in software on their end.
