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.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
