Why aren't programs written in Assembly more often? [closed]
...ur old code can easily make use of the new instructions.
What if the next CPU has twice as many registers?
The converse of this question would be: What functionality do compilers provide?
I doubt you can/want to/should optimize your ASM better than gcc -O3 can.

...ver服务，在启动之前，需要先解决一下可能最影响情绪的问题：我们知道windows services默认情况下是用本地系统账户运行的，可一般情况下我们会在当前操作用户下设置对vss共享目录的访问权限，比如当前windows运行账户为administra...
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...

...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.
