The best approach is to try it first without an extra field, measure the performance, and if it really turns out to be too slow, you try to optimize. …

What about a more DRY version, where even the code visible =is not repeated over and over again? foreach(var btn in new[]{lnkbtn1, lnkbtn2, lnkbtn3}) btn.visible=false; IMHO that will scale b …

My idea is first I make this table: CustomerId ItemId Total_Cost That's ok, there is no way around this, you will need to determine the total price sum per item and per customer first before y …

For this kind of domain, it is is not uncommon that you need bidirectional lookup: quick access to the coordinate of an enemy (or more general, of any kind of piece) quickly determine which piece is …

In the domain of just-in-time compilers, improvements in compiler software has increased application performance by around an order of magnitude in the last 10-20 years. … real increasement was less since application performance depends also on other hardware components like memory access speed, hard drive speed, GPU speed etc). …

Call it "missed occasion for performance optimization by using bulk operations instead". … My point is: performance should not be the only, perhaps not even the first criteria for deciding which solution is better, also think about maintainability. …

If you want to profile just one function, and you know the small number of input combinations you are interested in, you can add some kind of "switch mechanism" which will make the calls visible in an …

Quicksort does not outperform all other sorting algorithms. For example, bottom-up heap sort (Wegener 2002) outperforms quicksort for reasonable amounts of data and is also an in-place algorithm. It i …

This gives you an opportunity to measure the performance impact - and prove or disprove managements objections. …

Here is a simple improvement which will most probably meet your time constraints. For every divisor i of N, there is also a corresponding divisisor N/i. Thus to find all pairs of divisors, you need on …

The size only matters from a performance perspective when you copy objects around, when you store them to disk or a database, or when you are accessing the data of so many different objects that your CPU … So is an accumulated effect, and I doubt it counts as "performance impact caused by access to one of its members through a reference". …

You could read the available folder names just once, and store their names in a local file. When the macro is run again, read that file into memory and use it to find the full folder name for a given …

after only one week, DailySales table will become so huge that the database will be cumbersome to manage I question that. I have been using MS Access regularly for more than 20 years, and used it …

In case performance really turns out being not acceptable, then you should start thinking about improving it, not beforehand. … Experimenting with ideas from #1 or #3 might help, but make sure you only sacrifice readability of your code when it is absolutely unavoidable to meet the performance goals. …

Each of the 3^25 combinations can be interpreted as a 25 digit number in base-3 number system. So there is a one-to-one correspondence between those numbers from 0 to 3^25-1 and those combinations / …
