SQL Server does not cache the query results, but it caches the data pages it reads in memory. The data from these pages is then used to produce the query result. You can easily see if the data was read from memory or from disk by setting SET STATISTICS IO ON Which returns the following … Read more
I was able to hunt down some helpful documentation. SizeLimit does not have units. Cached entries must specify size in whatever units they deem most appropriate if the cache size limit has been set. All users of a cache instance should use the same unit system. An entry will not be cached if the sum … Read more
The main reason is: performance. Another reason is power consumption. Separate dCache and iCache makes it possible to fetch instructions and data in parallel. Instructions and data have different access patterns. Writes to iCache are rare. CPU designers are optimizing the iCache and the CPU architecture based on the assumption that code changes are rare. … Read more
There are two basic options: disable the caching altogether (the caching is done with the cacheprovider plugin): pytest -p no:cacheprovider -p is used to disable plugins. changing the cache location by tweaking the cache-dir configuration option (requires pytest 3.2+) Sets a directory where stores content of cache plugin. Default directory is .cache which is created … Read more
There are several ways you can do this and the right answer depends on your usage of the cache. You have a “main” cache manager If you use CacheManager A for 90% of your use case and B for 10% I’d advise to create a default CacheManager for A (you’ll need to specify it via … Read more
It stores the presence or absence of a favicon in History. If you want to reset it, clear your History. Here is a comprehensive FAQ. Edit: Quoting the blog, calling it an extensive answer: why doesn’t the favicon for my site appear in IE7? This is a re-posting of a post originally published on 2007-03-01. … Read more
I believe the issue is that when you cache the fragment in your view, a cache digest is being added to the cache key (views/all_available_releases/41cb0a928326986f35f41c52bb3d8352), but expire_fragment is not using the digest (views/all_available_releases). If you add skip_digest: true to the cache call in the view it should prevent the digest from being used. <% cache … Read more
You can use the VaryByCustom parameter for this. In your user control you would have the following: <%@ OutputCache Duration=”1000″ VaryByParam=”None” VaryByCustom=”MyKey” %> Then you would override the GetVaryByCustomString method in your Global.asax like so: public override string GetVaryByCustomString(HttpContext context, string arg) { if (arg == “MyKey”) { object o = context.Current.Application[“MyGuid”]; if (o == … Read more
I want to know which approach is a better in terms of performance and maintainability. As always, you have the tools to figure it out. Code both possible solutions and make them race. The one that wins is the winner, you don’t need anyone here to answer this particular question. About maintenance, the solution that … Read more
