c# - WCF hosting and Performance -

-

i have wcf service. have done testing basichttp binding , tcp binding.

in console client created hundreds of threads , hit service tcp , http binding. turned out tcp twice faster http.

then made web client runs on iis , hits service. turned out http faster tcp.

how happen? isnt tcp supposed faster basichttp? code 1 below. similar.

stopwatch start here  thread[] ts = new thread[100];   for(int i= 0; i< ts.lenght;i++){     ts[i] = new thread(foo);  // replace bar second test.   ts[i].start();   }  for(int 0;i< ts.lenght;i++){     ts[i].join();   }    stopwatch stop here.  public static void foo(){   myserviceclient myclient = new myserviceclient("nettcpbinding");   myclient.getresult(1);   }   public static void bar(){ myserviceclient myclient = new myserviceclient("basichttpbinding"); myclient.getresult(1); }

did know wcf has throttling turned on by default. before run these tests, should turn off using bit of config in web.config's servicemodel section:

<behaviors>   <servicebehaviors>     <behavior> <!-- can omit name in .net 4 -->       <servicethrottling          maxconcurrentcalls="10000"          maxconcurrentsessions="100000"          maxconcurrentinstances="100000" />     </behavior>   </servicebehaviors> </behaviors>

the defaults vary version around 16, 10, 100 or along lines in .net 4. lower defaults applied even if have no throttling entry in web.config / app.config.

good luck.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
