I'm using a Dictionary<> to store a bazillion items. Is it safe to assume that as long as the server's memory has enough space to accommodate these bazillion items that I'll get near O(1) retrieval of items from it? What should I know about using a generic Dictionary as huge cache when performance is important? EDIT: I shouldn't rely on...
I have an application that periodically needs to process large blocks of data with a computationally trivial algorithm. It turns out I can also prevent slowing down the system from hard drive accesses by keeping the blocks of data in a memory cache. The application is a low-priority application so I'm working to minimize its impact on th...

How do browsers deal with a full cache? Presumably they all make some kind of decision on what to throw away based on file size, expiration time and so on? Anyone know where I can find details? Google just returns a load of pages about manually clearing caches. ...

Hi, I am doing a iPhone game using cocos2d that involves a huge set of character animations (atleast 25 different of them).. for which I am having a lot of spritesheets each weighing around 100KB to 200KB.. And I used to create the AtlasSpriteManagers for these on-demand. But when I tested this in the device, there was lotsa performance...
I have Django running in Apache via mod_wsgi. I believe Django is caching my pages server-side, which is causing some of the functionality to not work correctly. I have a countdown timer that works by getting the current server time, determining the remaining countdown time, and outputting that number to the HTML template. A javascript...
I have to cache an object hierarchy in-memory for performance reasons, which reflects a simple database table with columns (ObjectID, ParentObjectID, Timestamp) and view CurrentObjectHierarchy. I query the CurrentObjectHierarchy and use a hash table to cache the current parents of each object for quickly looking up the parent object ID,...

Hi, We are thinking to make some architectural changes in our application, which might affect the technologies we'll be using as a result of those changes. The change that I'm referring in this post is like this: We've found out that some parts of our application have common data and common services, so we extracted those into a Globa...

What is the standard way to manipulate the data-cache on linux from a user-mode program? I'd like to writeback and invalidate the data-cache of a memory region that that is shared between my user-mode program and a peripheral device. Linux has no driver for it, and writing one myself would be overkill for the simple things I want to ...
