The application may be doing too much work on its main thread
... in a vast array of hardware unlike ios
and windows devices. The RAM and CPU varies and if you want a
reasonable performance and user experience on all the devices then you
need to fix this thing. When frames are skipped the UI is slow and
laggy, which is not a desirable user experience.

Serving gzipped CSS and JavaScript from Amazon CloudFront via S3
...p into your build/deployment scripts. The advantages are:
It requires no CPU for Apache to gzip the content when the file is requested.
The files are gzipped at the highest compression level (assuming gzip -9).
You're serving the file from a CDN.
Assuming that your CSS/JavaScript files are (a) m...
Custom CSS Scrollbar for Firefox
...and has loads of parameters you can tweak, but it ended up being a bit too CPU intensive for me (and it adds a fair amount to the DOM).
Now I'm giving Perfect Scrollbar a go. It's simple and lightweight (6KB) and it's doing a decent job so far. It's not CPU intensive at all (as far as I can tell) a...
Postgres: “ERROR: cached plan must not change result type”
...stgres 10 instance, enabling the conservative setting does result in extra CPU usage on the database server. It wasn't much though, I could only even see the autosave functionality show up as using a measurable amount of CPU after I'd tuned every single query my load test was using and started push...
Asynchronous vs synchronous execution, what does it really mean? [closed]
...tart and end points of tasks A, B, C represented by <, > characters.
CPU time slices represented by vertical bars |
Technically, the concept of synchronous/asynchronous really does not have anything to do with threads. Although, in general, it is unusual to find asynchronous tasks running on...
Is there a performance impact when calling ToList()?
....CopyTo(). This operation is quite efficient and probably will map to some CPU instruction for copying blocks of memory. However, in terms of performance memory is required for the new array and CPU cycles are required for copying all the elements.
Otherwise the size of the source collection is unkn...
Volatile Vs Atomic [duplicate]
...e Thread there is no problem in doing that. So if it is convenient for the CPU (i.E. batch-writing of memory), reordering in that way is very much possible.

C# switch statement limitations - why?
...C# compiler. Of course, this isn’t final, as the actual instructions the CPU runs are then created by the JIT.
I have checked the final CPU instructions actually executed on my x86 machine, and can confirm a simple adjacent set switch doing something like:
jmp ds:300025F0[eax*4]
Where a ...

... method. This is a big one, it makes property accessors essentially free.
CPU register allocation. Local variables and method arguments can stay stored in a CPU register without ever (or less frequently) being stored back to the stack frame. This is a big one, notable for making debugging optimiz...
How do I specify the platform for MSBuild?
...ution must be configured for both platforms. Actually you just have an Any CPU configuration.
How to check the available configuration for a project
To check the available configuration for a given project, open the project file (*.csproj for example) and look for a PropertyGroup with the right Co...
