performance difference in Webservice -'Normal' wayI'm new to WebServices, and I'm doing some tests (with a small VB.NET-application) to know the performance-difference between a WebService and the 'normal'-way of getting data (just connecting directly with a SqlDataAdapter to the SQL Server). The WebMethod simply gives a DataSet back, and does exactly the same actions as the normal-Method does. The difference are enormous in my opinion: 1 record: WebService: 0,03125 seconds Normal: 0,0156 seconds ->only 50% of WebService 10 records: WebService: 0,0468 seconds Normal: 0,016 seconds -> only 33,33% of WebService 100 records: WebService: 0,125 seconds Normal: 0,0156 seconds -> only 12,5% of WebService 1000 records: WebService: 1,14 seconds Normal: 0,93 seconds -> only 8,22% of WebService How does this come? The webservice is even local! So I guess it will take much more time when it wil be on another Server... Is there a way to have a better performance? and why using WebServices if they score so bad in performance? Thanks a lot in advance for any hints etc Pieter 1. Do your tests in a loop 100 times. Or 1000 times. That will be more
accurate. 2. Web services take time because the request has to be packaged and sent. Data has to be serialized and deserialized. Requests have to be processed and responses sent. Even if it all on the same machine. But yes, calling a web service will always be slower then executing code directly. That is why you don't want to do it unless your application requires it.

And isn't there any way to to speed things up a little bit? The fact is: in my case it could be helpfull, because it should be used by our own people (Windows Forms application), and give a consultancy-option to our Clients (Web interface). But why are people giving such an importance to XML Webservices? I know some big software-companies that pass everything by a WebServices, even local Windows forms applications. I was alreaddy sceptic about the technique, but now I am even more sceptic to use it... :-/ Show quoteHide quote "DraguVaso" <pietercou***@hotmail.com> wrote in message news:OdOG6X$eFHA.3864@TK2MSFTNGP10.phx.gbl... > Hi, > > I'm new to WebServices, and I'm doing some tests (with a small > VB.NET-application) to know the performance-difference between a > WebService > and the 'normal'-way of getting data (just connecting directly with a > SqlDataAdapter to the SQL Server).

"hot stuff" is discussed likely more without necessarily reflecting real use. You could try a monitoring tool to make sure it goes into serializing/http transmission/deserializing. By constrast ADO.NET uses the native SQL Server protocol. For now it doesn't look that bad to me. IMO the real question is how much often do you need to call this ? It greatly depends on the kind of application you are writing (for some applications you could even use a "checkout", "checkin" model that would allow to work locally a while before making new data available). In any case you are not forced to use web services if this is not needed... -- Show quoteHide quotePatrice "Andrew Morton" <a**@in-press.co.uk.invalid> a écrit dans le message de news:eNa4ZuLfFHA.1044@tk2msftngp13.phx.gbl... > DraguVaso wrote: > [snip] > > But why are people giving such an importance to XML Webservices?

My opinin is different time is not at all issue for today's high speed processor. you can compromise time by compatible hardware.but in future if you need to built onother application for your company then you can use existing web services and devlopment will be faster -- Show quoteHide quoteHave A Good Day, Mahesh, Maheshmandh***@yahoo.co.in "DraguVaso" wrote: > Thanks! > And isn't there any way to to speed things up a little bit?

Will my Webservice have much better performance when turning on a real server (better processor, more ram) than my local pc? Or will the network-than consume more?

Try to understand my point ,if you run the same code on 64 bit machin performance will always be greater that 32 bit machin isn.t it? My point is this doesn't affects applications that much than what web service gives us i.e. ability to built destributed application with fare ease and less complexity. there is another way also . net remoting which gives better performance but it is platform specific.if you are building distributed applications ondifferent platform then there is no choice for you. you can not use 'normal'-way of getting data. Thats benifeet of webmethods\ -- Show quoteHide quoteHave A Good Day, Mahesh, Maheshmandh***@yahoo.co.in "DraguVaso" wrote: > What do you mean with "compatbile hardware"? :-) > Will my Webservice have much better performance when turning on a real > server (better processor, more ram) than my local pc?

With a webservice that is to day the transport of the data. Because the fact that the format using it direct is not the same as using a webservice, will there always be a difference. For that are no absolute figurs to give, because with one active user on a 1Gb Ethernet Lan, that will be much quicker than with 100 users on a 2Mb Ethernet Lan. In my opinion has the speed always to be in a way that it is for the user comfortable. To get it in one milliseconds or 500 millisecond is mostly not important because the user will normally not see that (mostly is with a sent or get of data a natural restpoint of the usere involved, so it can be even take some more time until maximum 3 seconds before there is a wait text needed). I hope that this gives an idea. Cor
