I agree, and since yesterday I have worked on implementing buffering, which is now operational.
But it seems that something far stranger is going on, as I tried a buffer that can hold the entire file in memory, and only write it at the very end. Still my number of reads explode when the program is running, and I have found out that the major part of the reads that Task manager is counting are done where my program does what calculations, and other stuff, none of which involve I/O at all....
Some of my method calls seem to generate I/O just by performing simple calculations, or filling an array with numbers, and such.
The file you are reading and writing is actually 1MB; not 16MB.
"Reads" and "writes" are usually buffered; in your case however, due to "positioning", you seem to be losing the benefits of buffering in your reads.
While "logically", you are only reading about 1MB, in actuality, you are reading about 4GB with each iteration.
Sector sizes / allocation units are running around 4KB these days; this is what you are transferring between disk and memory for each one of your reads; and why you are seeing those high transfer rates (300MB/sec).
Unless this is some specific "disk exercise", I suggest you do all your "reading and writing" to a byte array and then just write the whole thing out when you're done.
(Depending on the speed and memory of your computer, this may also be a factor in this case; others may not notice the degradation).
I know about the file size, the program was to demonstrate the behaviour, not the actual program I am developing. When the program is done, some of the files that need processing will far exceed available RAM of any windows computer I know (TB size files).
I am developing a web application which has to make asynchronous calls because I have to make sure UI thread is not hanged.
In my application I have around 15 projects like SampleProject1, SP.BLSP, SP.Web, .. Also for every service call there is two minutes timeout.
I am trying to implement signalR in my code for waiting until each function is executed completely. Please see the following sample code.
After the first service call completed, it calls the second. The second call will surely takes more than two minutes. It might take more than 10 mins.
And I need to use results from first service call in second.
When implementing signalR, I tried to install Microsoft.Owin It asked for which project to add. I am trying to add SignalR Startup class in my SampleProject1.
I am not sure if:
1. SignalR is right way for doing this approach or not.
2. If I can use SignalR, in which project should I add this Microsoft.Owin
I tried google but most of them showed how to implement in new project and with out web service calls.
public partial class lengthProcess : UserControl
FirstWebServiceCaller1 FWbSvcCallr1 = new FirstWebServiceCaller1();
FWbSvcCallr1.Process1Completed += new EventHandler<request1completedeventargs>(FirstWebServiceCaller1_Process1Completed);
I'm not sure exactly what you were asking there, but it appears as though you want to know how to increase the timeout. Is this correct? If it is, you should look to configure the ConnectionTimeout as described here[^].
Your best bet is to collect some information:
1. The computer are you using (Make, Model, etc.)
2. On your computer investigate all of the installed devices using the device manager (found under Start/Settings)
3. Once you've found the device in question use the context menu and open the property dialog.
4. Go through all the tabs and see what drivers and dlls are installed for the device.
5. Use all of the above information to make intelligent queries on the internet using your favorite search engine.
6. Also contact the maker of your computer if the device came preinstalled and ask them about information of said device.

I'm going to make a video file from images on .NET using Aforge.Video.FFMpeg.dll.
But I have only FFMpeg.dll which compiled on .NET3.5.
I think compile .NET wrapper.
Unfortunately, I couldn't search Aforge.Video.FFMpeg source.
Out of randomness, I updated the library to the latest FFmpeg version. I have it as .NET 4.5.2, but I will gladly do a 4.5 build for you if you want. Do you need MSVC 11 (VS 2012) or MSVC 12 (VS 2013)? Or is either fine?
