Does pandas iterrows have performance issues?
... via SIMD instructions. Some parts of Numpy enable SIMD, depending on your CPU and installation process. The benefits to parallelism won't be as dramatic as the static typing and better caching, but they're still a solid win.
Moral of the story: use the vector operations in Numpy and pandas. They ...

How does BitLocker affect performance? [closed]
...r and core synchronization with no overhead, and that nothing requires the CPU in the same time (that one hell of an assumption, actually). The X25-M G2 is announced at 250 MB/s read bandwidth (that's what the specs say), so, in "ideal" conditions, BitLocker necessarily involves a bit of a slowdown....

Why main does not return 0 here?
...return value from a function is normally stored in the eax register of the cpu, so the statement "return 4;" would usually compile to
mov eax, 4;
ret;
and return x (depending on your compiler) would be something like:
mov eax, [ebp + 4];
ret;
if you don't specify a return value then the compil...
setTimeout or setInterval?
...to execute than the interval that is set for it, the browser will eat 100% CPU trying to service it, and may become less responsive.
Which do you use and why?
Chained-Timeout gives a guaranteed slot of free time to the browser; Interval tries to ensure the function it is running executes as cl...
Favourite performance tuning tricks [closed]
...he query plan - always.
Turn on STATS, so that you can examine both IO and CPU performance. Focus on driving those numbers down, not necessarily the query time (as that can be influenced by other activity, cache, etc.).
Look for large numbers of rows coming into an operator, but small numbers coming...
How to destroy an object?
...for "speed", but if you want to reclaim memory immediately (at the cost of CPU) should want to use null.
Like others mentioned, setting to null doesn't mean everything is reclaimed, you can have shared memory (uncloned) objects that will prevent destruction of the object. Moreover, like others h...
