Reducing memory usage by ISTIO side car


Reducing memory usage by ISTIO side car

may help you . You are right that #2 is a problem. There has been some discussion about this on the Istio mailing list: https://groups.google.com/forum/#!topic/istio-users/gRP4roSnHtQ
The bottom line is that the current implementation, where every service is configured to talk with every other service, is O(N^2) which doesn't scale. So far, there has only been some (mostly internal) early discussion about what the various options might be for pruning the sidecar config, but I think there will probably be some work starting in this area relatively soon.

Reducing memory usage of .NET applications?

Reducing memory usage of .NET applications?

I think the issue was by ths following , You might want to check out Stack Overflow question .NET EXE memory footprint. The MSDN blog post Working set != actual memory footprint is all about demystifying the working set, process memory and how to perform accurate calculations on your total in-RAM consumption.
I will not say that you should ignore the memory footprint of your application -- obviously, smaller and more efficient does tend to be desirable. However, you should consider what your actual needs are.

I wish this help you The first step is to know how to calculate the asymptotic memory usage, which means how much the memory grows when the problem gets bigger. This is done by saying that one recursion takes up X bytes (X = a constant, the easiest is to set it to 1). Then you write down the recurrence, i.e., in what manner the function calls itself or loops and try to conclude how much the memory grows (is it quadratic to the problem size, linear or maybe less?)
This is taught in elementary computer science classes at the universities since it's really useful when concluding how effective an algorithm is. The exact method is hard to describe in a simple forum post, so I recommend you to pick up a book on algorithms (I recommend "Introduction to Algorithms" by Cormen, Leiserson, Rivest and Stein - MIT Press).

hope this fix your issue First you should find out what kind of relatioship your banana->apple relation is. If it is a composition (A banana is composed of its apple and...) the simplest think is to store an apple instance in a banana.
code :
class banana
{
  apple apple_;  // a banana HAS A apple
};
class BananaRepository
{
  typedef XYZType BananaID;
  Banana& GetByID(BananaID  id);
  BananaID Add(Banana& b);
};
class BananaRepository
{
public:
  typedef std::vector<Banana>::size_type BananaID;

  Banana& GetByID(BananaID  id)
  {
    return bananas_.at(id);
  }

  BananaID Add(Banana& b)
  {
     bananas_.push_back(b);
     return bananas_.size() - 1;
  }

private:
  std::vector<Banana> bananas_;
};

Reducing memory usage with UIImagePickerController

Does that help Your processImage method is not your problem.
We can test your image-saving code by transplanting it into Apple's PhotoPicker demo app
code :
- (void)imagePickerController:(UIImagePickerController *)picker 
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];

    [self.capturedImages removeAllObjects];   // (1)
    [self.imagePaths addObject:[self processImage:image]]; //(2)

    [self.capturedImages addObject:image];

    if ([self.cameraTimer isValid])
    {
        return;
    }
    [self finishAndUpdate]; //(3)
}
static int imageName = 0;

-(NSString*)makeImageFilename {
    imageName++;
    return [NSString stringWithFormat:@"%d.jpg",imageName];
}
What are some best practices for reducing memory usage in C?

What are some best practices for reducing memory usage in C?

To fix this issue In C, at a much simpler level, consider the following;
Use #pragma pack(1) to byte align your structures Use unions where a structure can contain different types of data Use bit fields rather than ints to store flags and small integers Avoid using fixed length character arrays to store strings, implement a string pool and use pointers. Where storing references to an enumerated string list, e.g. font name, store an index into the list rather than the string When using dynamic memory allocation, compute the number of elements required in advance to avoid reallocs.
