VM running out of memory while getting images from the cache

人走茶凉 提交于 2020-01-03 03:20:14
问题 The problem that I'm addressing is known to be in devices with 16 mb of heap memory, and I need to solve it. I have threads getting images from a server (Big Images) and having them cached then displayed. The problem is that I run out of memory. To explain a little further I'm posting my log cat as well as some code: public class Test extends Activity implements OnClickListener { ImageView paint, wheels, shadow; Button b; int j = 2; int i = 1; String pathToWheels, pathToPaint, pathToShadow;

问题 I'm trying to fetch and cache some external resources/websites using a service worker.

问题 I am looking at the performance of OpenMP program, specifically cache and memory performance. I have found guidelines while back ago how to analyze performance with Vtune that mentioned which counters to watch out for. However now cannot seem to find the manual. If you know which manual I have in question or if you know the counters/events, please let me know. Also if you have other techniques for analyzing multithreaded memory performance, please share if you can Thanks 回答1: Here is an

Sitecore HTML cache and external data sources

天涯浪子 提交于 2020-01-03 02:31:26
问题 How would you handle a situation when you want to cache some sublayout that relies on external data(search index, etc.)? Here's the example: After updating content you click "Publish" in Sitecore. HTML cache is automatically cleared after publishing. Sublayout is rendered and put into the cache on first request, but the search index is not yet updated. Search index is updated. Until the next cache cleanup, sublayout will display the cached (obsolete) date. Are there any simple ways to fix

find the pages accessed by thread

泪湿孤枕 提交于 2020-01-03 01:47:09
问题 I am looking for some scheduling options based on data accessed by threads. Is there any way to find the pages of cache accessed by a specific thread. If i have two threads from two different processes, is it possible to find the common data/pages accessed by both the threads 回答1: Two threads from the same process are potentially sharing the whole process memory space. If the programme does not restrict access to certain regions of memory to the threads, it might be difficult to know exactly

What is the best way to cache and reuse immutable singleton objects in Java?

ε祈祈猫儿з 提交于 2020-01-03 00:52:29
问题 I have a class representing a set of values that will be used as a key in maps. This class is immutable and I want to make it a singleton for every distinct set of values, using the static factory pattern. The goal is to prevent identical objects from being created many (100+) times and to optimize the equals method. I am looking for the best way to cache and reuse previous instances of this class. The first thing that pops to mind is a simple hashmap, but are there alternatives? 回答1: There

Caching of Google Cloud Endpoints?

社会主义新天地 提交于 2020-01-02 14:13:09
问题 Will requests to Cloud Endpoints get cached? The official docs are a little light on this matter. The docs read: Cloud Endpoints uses the distributed Extensible Service Proxy to provide low latency and high performance for serving even the most demanding APIs. [...] and can be used with Google App Engine, Google Container Engine, Google Compute Engine or Kubernetes. A 'distributed extensible service proxy' makes me think the Endpoint is distributed to the edge nodes for faster responses, but

OutputCache attribute being ignored in MVC 3

巧了我就是萌 提交于 2020-01-02 11:59:07
问题 So I am having an issue with IE 7 being able to download a file from an SSL site built in MVC 3. For IE 7 to be able to save a file from an SSL site, it must be cache-able. The code for the method is: [OutputCache(Location = OutputCacheLocation.ServerAndClient, Duration = 20, VaryByParam = "none", NoStore = true )] public override FileContentResult Export(int? id, string extra) { ... return new FileContentResult(byte[], mimetype); } This working in IE9, Chrome,Safari, and Firefox.
