c# - Asp.net MVC real time application performance -

-

i'm trying create asp.net mvc web application ,some pages need show data in "real time" ,this data on sql server database ,the data changing created stored procedure in sql server , call procedure in controller using entity framework linq , send result browser using ajax used outputcashing minimize number of execution of stored procedure , in same controller there multiple methode use same stored procedure ,every methode execute same procedure , how emprove performance of application , there way execute stored procedure 1 time controller ??

this controller objective minimize use of database 

   [outputcache(duration = 20, varybyparam = "*")] public class jobsetlcontroller : controller {      private etl_rep_mauientities db = new etl_rep_mauientities();     public   objectresult<biogetetljobs_result> etljobs;      public jobsetlcontroller()     {           etljobs =db.biogetetljobs();       }      public actionresult indexp()     {          var y = xx in etljobs              xx.etat!="completed"              orderby xx.etat ascending                 select xx;         return partialview(y); }        public actionresult indexpall()     {          var y = xx in etljobs                     xx.etat == "completed"                 select xx;         return partialview(y);     }

if server not in web farm (multiple servers) can cache data in asp.net cache (this not output cacheing, it's data cacheing). set 5 minute time limit on expiration of data (you data needs update every 5 minutes) when controller needs data first checks cache, , if it's not there execute stored procedure.

mydata items;  items = (mydata)cache["mydata"]; if(items == null) {    items = doquerytoreturnitems();    cache.add("mydata", items, null, datetime.now.addminutes(5), ..); }

it's possible setup cache item dependent upon sqldependency when data changes, cache can updated.
