I was wondering if the CPU is the bottleneck. Hence I used the Performance
Monitor to look up some values. Here are the results.
Counter Scale Average Maximum
Minimum
%Disk Time 1 2.74 24.932
0
Current Disk Queue Length 10 0.090 6 0
Buffer cache hit ratio 1 99.752 99.752
99.751

Hi,
Does anyone know if there are any free performance monitoring tools
similar to Intel VTune. I need to be able to see how long I spend in
certain methods and how expensive some statements are.
Thanks!

My database is suffering from poor performance of late. Reports that
used to run in a reasonable time, now take a while. The explain output
show that the query is fully indexed, and the statistics are up to
date. Using a statement monitor I was able to determine that a
particular query took 545 seconds of real time to run, yet only 19
seconds of CPU. According to my system monitoring tools, I had plenty
of idle CPU cycles and free memory...

Folks,
I am not sure what I am doing wrong, but We have an transaction that
does some serious calculation on small chink of data over and over
again.
It selects few rows from the table several times and does different
calculations. It was taking about 45 seconds to run. I thought that
moving the file to its own tablespace and giving it large bufferpool
would improve the performance. I experienced exactly opposite, the

As a refresher, a description of my problem is in the message body below.
I could not get answers to all of the questions that were asked below in a
previous thread, but here is what I found out:
1. Number of LOB's inserted per hour and average size
2. Number of LOB's updated per hour and average size
3. Number of LOB's deleted per hour and average size
4. Rough estimate of the amount of non-LOB data inserted, updated, and
deleted per...

Hi
I would like some general pointers about monitoring some performance
parameters of an application we have written. For example: how many threads
it has currently running, how long the threads take, how much memory the
application is using, what percentage of cpu capacity the application is
using.
I assume a good idea would be to use a PermanceCounter (or several). I have
read a little about them on the web, but I've not really come...

Greetings,
Lets say I have this class written in standard C++. I want to expose it to
C# programs. So lets say I create a ref class to "wrap" around the standard
C++ class. What are the performance implications of doing so?
For the sake of clarity, the class is currently written in C#. It is a CPU
emulator. C# performs well, but after rewriting it in C++/CLI it performs
even better. But I'd like to rewrite it in standard C++ and...

Hello,
could you please advice on how to measure replication performance
in Oracle, DB2 & MS SQL Server RDBMS installed in Windows servers ?
I've got two servers with databases installed and configured,
I prepared set of data using DBGEN from TPC and I already imported them
into databases.Also, I configured the replication.
Now I have to do a test with a few kind of replications method

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...

Overview:
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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...
