c# - Benchmarking code precisely -

-

I need to measure the performance of my code with the maximum possible precision I

Currently I use I am doing:
- Stopwatch for measuring from time to time - Set process intimacy to use all CPU cores - Set maximum thread preference - Display warm-up before measuring - 1000 times Test and calculate average

However, I run benchmark C 1% difference between the maximum) I how a measure to make more precise the measurement?

This may be obvious, but your CPU is not dedicated to your single process, Also works for many things I

In addition, the behavior of memory usage, HDD usage and GC behavior can vary between hanging. Your computations may require virtual memory, which is much slower than RAM access. And so on ...

About GC, you can try to play with various settings of "GCSettings.LatencyMode" to see if anything changes it (for example See).

The same session, stopwatch on the same computer is quite accurate: If the duration is different between execution, then it is probably not due to the lack of accuracy in the measurement, because this process does not take at all ... Obviously, each of your tests should be "repetitioned" at least a few hundred milliseconds, the stopwatch will never be able to measure a period in nanosecond ...

and 1% difference at all Not surprisingly Is In.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
