Hi All,
Out of nowhere my udb system (v8) performance has went terrible. Its gotten
about 10x worse, (some tests that used to take 2 seconds to run now take
20)... I'm not sure what happened. I did reorg/runstat/rebind on
everything, no luck... I'm not sure what to do next...? Any recommendations
on something to try to start narrowing down the possible problem.
Things I've tried:

And here's what I am getting:

Hello,
I am trying to isolate some performance issues.
The database is DB2 v8.1 running on a Win2000 server with 4 processors and
1gb of RAM.
The application is a GIS application that uses ADO to access the database.
It was not written specifically for DB2 and I think almost all queries are
running as dynamic queries. The performance issue arise when users are

Hi,
I have a large table (about 50G) which stores data for over 7 years. I
decided to split this table up into a yearly basis and in order to
allow minimum changes to the applications which access this table, I
created a union all view over the 7 yearly tables.
What I have noticed is that queries against the union all view is
considerably slower than queries against the original table. When I ran
db2batch, I noticed cpu usage was higher...

Because of historical reasons, I have both C# and C++ managed/unmanaged code
mixed together in my class library.
But I prefer to port code to C# since it compiles faster and the syntax is
much more readable so I can do more in less time.
The big question now, will I gain/lose performance, given the fact that I
create pure managed code, if I port the managed C++ classes to C# classes? I
cannot port all the classes at once, too much to...

I was wondering what performance advantages (or ramifications for all I know)
might be apparent if you used Managed C++ (MC++ from know on) instead of C#?
I know C# is a pure .NET language since it was made for the .NET Framework,
but because of my code has been migrated from Java, I need to make a few API
calls outside of the CLR. I'm quite new to C#, cause I'm more familiar with
Java and C++, but I would assume that any programmatic...

1. What work is in progress to bring C# performance closer to C++/CLI? Can we
expect C# to equal C++/CLI performance? If so when?
2. Also what work is in progress to improve MSIL/CLR/JIT performance in
general? As relases to the Framework e.g. 2.1, 2.2,.. are made do these
include performance imporovements?

hello,
I'm having a performance issue with a Windows CLI/ODBC application
that connects to a DB2 rel 7.1 on a mainframe of a bank.
I have to say I'm pretty new with this kind of environment.
The application is working, but it is much slower than when I run
against a DB2 7.1 on a poor Linux machine(using the same amount of
data in the tables used by the application).
I made some trace and I found the most noticeable difference is in the...

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
Here is the code in...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
