Is there a tool that would show me for a specific file on disk, how fragmented it is? (How many seeks does physical disk need to make if I were to read that file in a linear fashion)

Suppose I have a memory pool object with a constructor that takes a pointer to a large chunk of memory ptr and size N. If I do many random allocations and deallocations of various sizes I can get t...

I need some clarifications for the concept & implementation on memory pool. By memory pool on wiki, it says that also called fixed-size-blocks allocation, ... , as those implementations ...

Are there any sources where I can find different pcaps samples for IP fragmented data (WireShark compatible)?

I have a 20 gig table that has a large amount of inserts and updates daily. This table is also frequently searched. I'd like to know if the MySQL indices can become fragmented and perhaps need to b...

My application does a good deal of binary serialization and compression of large objects. Uncompressed the serialized dataset is about 14 MB. Compressed it is arround 1.5 MB. I find that whenever I...

I'm currently working on a project for medical image processing, that needs a huge amount of memory. Is there anything I can do to avoid heap fragmentation and to speed up access of image data that...

Many years ago, I was admonished to, whenever possible, release resources in reverse order to how they were allocated. That is: block1 = malloc( ... ); block2 = malloc( ... ); ... do stuff ... f...

I'm writing a qt-based c++ application and i need to be able to detect memory fragmentation in order to check if the current system can actually sustain the memory load: the program load a big imag...

Can anyone provide the script for rebuilding and re-indexing the fragmented index when 'avg_fragmentation_in_percent' exceeds certain limits (better if cursor is not used)?

I have a few ideas I would like to try out in the Disk Defragmentation Arena. I came to the conclusion that as a precursor to the implementation, it would be useful, to be able to put a disk into a...
