"HT/SMT" = hyperthreading?

Yes.

but you can compare it because 2 Bulldozer cores are also not 2 real cores. 

(Wikipedia) "The "module", described as two cores, can be contrasted with a single Intel core with HyperThreading. The only difference between the two approaches is that Bulldozer provides dedicated schedulers and integer units for each thread, whereas in Intel's core all threads must compete for available execution resources. "

Amd is calling that CMT (Clustered Multi-Thread)

So the hierarchy would be "2 cores > 1 CMT core > 1 SMT core".

yes.

and here some Benchmarks:

AMD Opteron 3280 (Kaphost): 5722 Points
http://www.cpubenchmark.net/cpu.php?cpu=AMD+Opteron+3280


Intel Core i7-3770 @ 3.40GHz(ATFclan.eu): 10359 Points
http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-3770+%40+3.40GHz


as you can see I7 of Hetzner (ATF) is almost twice as fast as the opteron of Server4you (Kaphost).

CPU is always not full, and single-core performance for each BL instance will be fine.

I've never seen full CPU usage on a server except for crashed servers (Gravity Cat's usually does this) and Glass' server.

As long as single-core performance is OK, then it's all about total power. For some reason 32-bit Windows programs can only use up the power of one core, however this can be spread across multiple cores. I have no idea how it works. It's a non-issue. Not sure if Lub boasted about single-core performance, but if he did, he has no loving clue what he's talking about.

It has to do with threading, not "bitness". A thread is always executed sequentially, so it can only be scheduled to one core at a time. Since Blockland is single-threaded it will only ever use the "total power" of one core.

I do see 5-8 threads (open resource monitor) on most servers that are running. Is that the same thing?

I remember changing to 64-bit Java and suddenly I could use both CPU cores on my computer. I assumed the diagnosis was straight forward in that it has to do with 32-"bitness".

I also note that Blockland.exe can't use more than 12.5% CPU (octocore, 100/8)

Are Java threads (at the user's code level, not java.exe's) the same thing? I've never experimented with it.

I'm not 100% sure, but I'd guess so. However, they're probably only used for light work, since Torque itself is mainly based on a single main thread running an event loop.

Java used to use "green threads", but abolished them in favour of native threads in 1.2/1.3.

Deathrider is Ddosing

We have proof, he was on Rein's server.
