If you want to cache an action, based on all the query parameters (or say on nearly all of them), you can do: caches_action :my_action, :cache_path => Proc.new { |c| c.params } Or, maybe you want all but some params that you just use for Analytics (but that have no bearing on the records you’re … Read more
L1 is very tightly coupled to the CPU core, and is accessed on every memory access (very frequent). Thus, it needs to return the data really fast (usually within on clock cycle). Latency and throughput (bandwidth) are both performance-critical for L1 data cache. (e.g. four cycle latency, and supporting two reads and one write by … Read more
CacheBuilder.build() returns a non-loading cache. Just what you want. Just use Cache<String, String> cache = CacheBuilder.newBuilder().build();
This is the one I use to fix the exact same thing when I ran the PageSpeed Addon: <FilesMatch “\.(jpg|jpeg|png|gif|swf)$”> Header set Cache-Control “max-age=604800, public” </FilesMatch> This goes into your .htaccess file. Read up on this page for more information about how to set cache for additional file types and/or change the cache length: http://www.askapache.com/htaccess/apache-speed-cache-control.html
Because it’s specified by Java Language Specification. JLS 5.1.7 Boxing Conversion: If the value p being boxed is true, false, a byte, or a char in the range \u0000 to \u007f, or an int or short number between -128 and 127 (inclusive), then let r1 and r2 be the results of any two boxing conversions … Read more
You could use the RemoveOutputCacheItem method. Here’s an example of how you could use it: public class HomeController : Controller { [OutputCache(Duration = 60, Location = OutputCacheLocation.Server)] public ActionResult Index() { return Content(DateTime.Now.ToLongTimeString()); } public ActionResult InvalidateCacheForIndexAction() { string path = Url.Action(“index”); Response.RemoveOutputCacheItem(path); return Content(“cache invalidated, you could now go back to the index action”); … Read more
Redis is a (sort of) in-memory noSQL database; but I found that my copy (running on linux) dumps to /var/lib/redis/dump.rdb
The solution I ended up using involved MemoryCache in the System.Runtime.Caching namespace. Here is the code that ended up working for caching my collection: //If the data exists in cache, pull it from there, otherwise make a call to database to get the data ObjectCache cache = MemoryCache.Default; var peopleData = cache.Get(“PeopleData”) as List<People>; if … Read more
HttpRuntime.Cache only provides severals methods and I think I’m able to implement these methods with Dictionary by myself. You think wrong. HttpRuntime.Cache is much more than a simple dictionary. It offers thread-safety and cache expiration policies. It provides possibilities of using custom implementation and benefit from distributed caching which is helpful in web farms. Implementing … Read more
Both of these depend on the CPU. There are CPUs which have no cache at all, there are CPUs which have the L1 cache on die and the L2 cache on a separate die on the same chip or even on a separate chip, or there are CPUs which have both L1 and L2 cache … Read more
