comment Configure a Linux router for fair bandwidth allocation without unnecessary limiting it
@jstarek Assuming that's true, what's the good way to delay ACKs right now?

comment Email Server IP Address is Blacklisted
Did you follow the links in the error messages you got? They should provide explanations.

comment Email Server IP Address is Blacklisted
If that 41.78.60.33 is accurate, you still have no reverse DNS.

comment Terminating a high volume of SSL connections cost effectively on EC2
Are you assuming each of those SSL connections forms a new session? Or are you testing with some level of session reuse? It makes a huge difference.

comment Is it possible to wake a computer connected directly to its NIC?
Is the port lit up on both sides even when the computer is off? If not, then wake on LAN isn't correctly configured or isn't supported.

comment Is a retransmitted SYN *EXACTLY* the same as the original?
He's almost certainly confusing rejection of stale packets from old connections with handling duplicate SYNs.

comment Which wildcard SSL cert vendors allow you to set up the same cert on multiple servers?
Believe it or not, there are CAs that make you execute a licensing agreement that limits the number of servers you can use the certificate on. Strange but true.

comment Server Processor Selection Criteria & Profiling
You said that you don't care about I/O or RAM and all your application is totally CPU bound. That's the situation where a synthetic CPU performance benchmark is perfect, especially when comparing CPUs with very similar architectures.

comment Best way to connect two separate networks with separate internet connections within the same building
192.168 addresses are private. If the networks use non-overlapping private addresses, you can just route between them. Do not exchange default routes, just private network routes.

comment Server Processor Selection Criteria & Profiling
The PassMark CPU rating is a pretty good measure of the total raw CPU capability of all cores put together.

comment Best way to connect two separate networks with separate internet connections within the same building
Do the networks use public IP addresses for all machines, private IP addresses, or some of each? If any private IP addresses are used, do they conflict? Is dynamic routing (like OSPF) already in use on either or both networks? Your whole game plan will depend on the answers to these questions.

comment Setup BIND to transfer the zone file for every Second Level domain for a gTLD?
For some TLDs, this is possible. For example, many country-level TLDs with small numbers of second-level domains, permit this.

comment Where did the free space go?
That "493G" you see there is actually 493GiB, which is equal to 530GB. So it's 70GB missing, not 100.

comment Is there a way to get an email when system starts using swap space for memory?
You want to know if your server isn't responding or isn't responding well. Don't try to look for memory usage specifically. (Except perhaps in addition to basic response monitoring.)

comment Linux: how many disk I/O does it take to read a file? How to minimize it?
Exactly. This is a consequence of very limited RAM and a filesystem design based around the idea that RAM is scarce and precious.

comment FTP Transfer Very Slow When Windows Firewall Enabled
It's not unusual for more than one thing to be wrong. Trust me, it's much better to fix things before they cause breakage than after. What else is the firewall blocking?
