...
Okay, but what is the memory required and CPU requirements for this optimal config. Or how do i take in the consideration of CPU and Memory also for this optimizations.

How do I return multiple values from a function? [closed]
... a new one), creating the namedtuple class is relatively expensive in both CPU and memory, and all class definitions intrinsically involve cyclic references (so on CPython, you're waiting for a cyclic GC run for them to be released). It also makes it impossible to pickle the class (and therefore, im...
What is the native keyword in Java for?
...is could be used to:
write faster code on a critical section with better CPU assembly instructions (not CPU portable)
make direct system calls (not OS portable)
with the tradeoff of lower portability.
It is also possible for you to call Java from C, but you must first create a JVM in C: How to ...

...asic library search path, with names like sse2 corresponding to additional CPU capabilities.
These paths, with hwcap in the line, can contain additional libraries tailored for these CPU capabilities.
One final note: using -p instead of -v above searches the ld.so cache instead.

...age collector is taking an excessive amount of time (by default 98% of all CPU time of the process) and recovers very little memory in each run (by default 2% of the heap).

Best practice for creating millions of small temporary objects
... is not always the case. A lot of objects you create does not even leave a CPU register. For instance, consider this for-loop

Let's not think about loop unrolling (an optimisations that the JVM heavily performs on your code). If max is equ...
