Hi,
I have been running some queries against a table in a my database and
have noted an odd (at least it seems odd to me) performance issue.
The table has approximately 5 million rows and includes the following
columns:
DocID (INTEGER, PRIMARY KEY, CLUSTERED)
IsRecord (INTEGER, NONCLUSTERED)

I know that's an old dirty issue; GDI+ almost -the slowest part of the
framework - has bothered many developers using it in animations. Even in
managed C++ the performance is awful.
Now, any dude out there does know any thing about this issue in VS 2005 +
..NET 2.0 ? Has Microsoft solved this performance problem, or we will have to
again stick to that DX for simple animations in our applications?
( and since Microsoft doesn't support DDraw...

I've encountered a troublesome inconsistency in the C-language Perl
extension I've written for CPAN (Digest::SHA). The problem involves the
use of a static array within a performance-critical transform function.
When compiling under gcc on my big-endian PowerPC (Mac OS X),
declaring this array as "static" DECREASES the transform throughput by
around 5%. However, declaring it as "static" on gcc/Linux/Intel
INCREASES the throughput by...

Ahmmm. It was my aim to match the performance of C and I achieved that
aim very early on. See, for example "The Design and Evolution of C++".

Hi
Has anybody had any experience of ASP.Net performance counters not updating.
In the performance monitor application when I try to add the groups ASP.NET
and ASP.NET Applications the counters all show 0. In addition, ASP.NET
Applications does not show any of the ASP.NET instances that are running on
the computer. The other counters for example % processor time work fine.
The problem machine is a test server running Win2003. ...

I'm currently building a website for one of the client. There has been
few errors here and there, but just recently the problem is getting worse.
Basically the symptoms is that when the user try to access the page, it
takes really long time to load. However, after up to 1 hour, the website
will run fine again as normal.
This issue has been there with the site. I usually just ask the system
admin to restart the IIS Service. However, the...

Hi -
Trying to chase down a baffling performance issue. Our database has been
running very slow lately. So we are performance tuning the database. In
doing so, we created a copy of our production database. In that database, I
changed one clustered index on a table to try to improve performance. I ran
one query - saw a slight improvement - but saw "lazy spool" in the execution
plan.
I tried to change it back to the original index by...

Hello Everyone,
I have a very complex performance issue with our production database.
Here's the scenario. We have a production webserver server and a
development web server. Both are running SQL Server 2000.
I encounted various performance issues with the production server with a
particular query. It would take approximately 22 seconds to return 100
rows, thats about 0.22 seconds per row. Note: I ran the query in single

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
