Hi,
I need to run an image processing application on a .NET server.
Do you have any tips what I should/can do?
I implemented the code in a webservice, but performance is very slow (at least 10x slower than when executed in a windows application).
Any help will be greatly appreciated.
thanks
I have been using CouchDB on some prototype applications and it has been brilliant, very easy to use and extremely quick. I was wondering if anyone has been using it in production and have any views on it's reliability, performance suitability for operational management etc ?? I am considering using it to support a service layer and would make use of its replication functionality.
Any comments/experiences would be most welcome.
What are your favorite C/C++ interview questions? It may be question or contain question of concepts, some subjects are:
Logic, multithreading, algorithms (and performance), STL, templates, inheritence, pointers.
This is a useful tool for me, to look at what would be tested on a career-like application.
Scenario
I have a C# application compiled as a DLL.
I have a build from last week and a build from this week.
There has been a significant change in performance so I want to compare the the two builds to see what has changed.
ANY IDEAS?........SUGGESTIONS?
Cheers
What's the difference between the two? They seem to have the same functionality at first glance.
Which one has faster performance which one is easier to use?
I am getting inling warning such as :
warning: inlining failed in call to ‘symbol_Arity’: call is unlikely and code size would grow
To get rid of this i changed the makefile adding the -Winline to get rid of this. I don't get any inlining warning. But , i don't know how wise is it to do in respect of performance. Can anybody please suggest me about it?
I always use If statement (In C#) as (1. Alternative);
if (IsSuccessed == true)
{
//
}
I know that there is no need to write "== true" as (2. Alternative));
if (IsSuccessed)
{
//
}
But, I use it because it is more readable and cause no performance issue. Of course, this is my choice and I know many software developers prefer first alternative. What is the best usage, and Why?
Can any one please share their experience on

Any Performance Issues?
There are many similar questions, but apparently no perfect match, that's why I'm asking.
I'd like to split a random string (e.g. 123xx456yy789) by a list of string delimiters (e.g. xx, yy) and include the delimiters in the result (here: 123, xx, 456, yy, 789).
Good performance is a nice bonus. Regex should be avoided, if possible.
We need to INSERT 2000 records into SQL DB from C# .Net code.
For this is there any way to INSERT all 2000 records at a time instead of executing the INSERT query for each record.
Also how would be the performance impact of doing this?
Thanks & Regards

Is it possible to execute raw commands as javascript through the Java driver for MongoDB?
I'm tired of wrapping everything in Java objects using Rhino, and would happily sacrifice performance for the convenience of passing javascript directly through to the DB.
If not, I can always use sleepymongoose or something, but I don't really want to add yet another language (python) to the stack at this point.
Any insights are appreciated.
Which type of index(clustered/non clustrered) should be used for Insert/Update/Delete statement in SQL Server. I know it creates an additional overhead but is it better in performance as comparison to non clustered index? Also which index should be use for Select statements in SQL Server?
I have been trying improve the performance of my game on iphone. Most of the cases, I do my all texture loading just before rendering the current frame. That makes big jerk in the frame rate. Anybody tried loading texture in secondary thread or something like that?
Very simple question: I want to optimize the following jQuery code with maximum readability, optimal performance and minimum fuss (fuss = declaring new variables etc):
$(".addthis_toolbox").append('<a class="addthis_button_delicious"></a>');
$(".addthis_toolbox").append('<a class="addthis_button_facebook"></a>');
$(".addthis_toolbox").append('<a class="addthis_button_google"></a>');
$(".addthis_toolbox").append('<a class="addthis_button_reddit"></a>');

I was told that putting too many files in a directory can cause performance problems in Linux, and Windows. Is this true? And if so, what's the best way to avoid this?
What allocators are available out there for use with STL when dealing with small objects. I have already tried playing with pool allocators from Boost, but got no performance improvement (actually, in some cases there was considerable degradation).
I know its supposed to improve performance and clean strings, but lets say there are no variables?
Might just be a
SELECT COUNT( `column` ) AS count FROM `table`
Should that be prepared?
Is there any case that a SELECT statement should not be prepared?
Anyone can give me an example on how to create local data caching? Like for example I query 10 millions records from my DB and I want to store it in my local so that I would not encounter performance problem next time when I want to reload the data. Thank you so much.
I've read some posts here and on the web about the differences of live() and delegate().
However I haven't found the answer I'm looking for (if this is a dupe please tell me).
I know the difference between live and delegate is that live can not be used in a chain.
As I also read somewhere delegate is in some case faster (better performance).
So I am wondering is there a situation where you would use live instead of delegate?
I know that this is a very objective question but I really want your opinion on this. What's the best right now in terms of comfort and performance? What do you use and why?

I'm currently using MSVC for C++ but as I'm switching to C to write a very performance-intensive program (interpreter) I have to search for a fitting C compiler.
I've looked at some binaries produced by Turbo-C and even if its old they seem pretty straigthforward and optimized.
Now I don't know what the best compiler for building an interpreter is, but maybe you can help me.
I've considered GCC but as I don't know much about it, I can't be really sure.
