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
for(int i=0, i<max, i++) {
// stuff that implies i
}
Let's not think about loop unrolling (an optimisations that the JVM heavily performs on your code). If max is equ...
Where do you store your salt strings?
...ach:
Since the exact logic is inferred at run-time, this approach is very CPU-intensive. The longer the length of the salt, the more CPU-intensive this approach becomes.
Authenticating incorrect passwords will involve the highest CPU cost. This can be counter-productive to legitimate requests, but...

Why use armeabi-v7a code over armeabi code?
...ices, but will be a lot slower, and won't take advantage of newer devices' CPU capabilities. Do take some benchmarks for your particular application, but removing the armeabi-v7a binaries is generally not a good idea. If you need to reduce size, you might want to have two separate apks for older (a...

What are the differences between a UIView and a CALayer?
...ore. Working with UIViews happens on the main thread, it means it is using CPU power.
CALayer: Layers on other hand have simpler hierarchy. That means they are faster to resolve and quicker to draw on the screen. There is no responder chain overhead unlike with views. Layers are drawn directly on t...
What is the optimal length for user password salt? [closed]
...pical three strikes locked out for 15 minutes is better. Are you "wasting" CPU cycles to do this? Yeah, whatever. The CPU spends more time idle than not on most websites anyway, so what does it matter? If you're running into performance issues, scale out.

Database sharding vs partitioning
...important to understand that databases are extremely resource intensive:
CPU
Disk
I/O
Memory
Many DBA's will partition on the same machine, where the partitions will share all the resources but provide an improvement in disk and I/O by splitting up the data and/or index.
While other strategies ...
