@MarcCliment: Which particular case? Which CLR? Which CPU architecture? On my machine I get a mixture of results. This is why I'm loathe to state/accept blanket statements such as "BTW, productionCollection1.ForEach(...) is more performant than AddRange". Performance is very rar...
Are static variables shared between threads?
...lem is more complex. Visibility of shared data can be affected not only by CPU caches, but also by out-of-order execution of instructions.
Therefore Java defines a Memory Model, that states under which circumstances threads can see consistent state of the shared data.
In your particular case, addi...

How do I parallelize a simple Python loop?
...ge(10)
def processInput(i):
return i * i
num_cores = multiprocessing.cpu_count()
results = Parallel(n_jobs=num_cores)(delayed(processInput)(i) for i in inputs)

The above works beautifully on my machine (Ubuntu, package joblib was pre-installed, but can be installed via pip in...
How to increase heap size of an android application?
... Not directly, for your app. Having more stuff may cause you to spend more CPU time going through that stuff, but the details there would depend on what you are doing with the memory and is not directly tied to having requested android:largeHeap. However, requesting a large heap may harm the user ex...
Do while loop in SQL Server 2008
... live in an age where our database servers have anywhere between 10 and 20 CPU cores idle at any given moment, and where our storage controllers have their available bandwidth measured in Gigabits, so I'm not sure this conventional "wisdom" that "LOOP = BAD" still applies.

Best way to serialize an NSData into a hexadeximal string
...e Gallagher's answer is sufficient for a relatively small size, memory and cpu performance deteriorate for large amounts of data. I profiled this with a 2MB file on my iPhone 5. Time comparison was 0.05 vs 12 seconds. Memory footprint is negligible with this method while the other method grew the he...
