Hi there,
I got a program to write data to a randomly accessed file (the program
moves file pointer to a certain position of the file according the
current "keyword" and then writes data). It compiles and runs in Win2K
and various Unix and Linux systems. The main program is in Fortran,
calling a data writing library writen in C++.
The weird thing is, it takes much longer elapse time (wall-clock time)
than CPU time (e.g., 20 min vs. 2...

Fellas!!
This is a very complicated one and it took me a few days to figure out
exactly what's going on, but here's the final story:
I have a production environment running on .NET with a SQL Server
(2000, SP3). The SQL Server is on a dedicated Proliant computer with
2GB RAM (the actual SQLServer.exe process has dynamic memory
assignment and can reach up to 1.6GB RAM). Nothing else is running on
that specific computer.

Hi,
Any suggestions on the following as I've kind of run out of ideas.
I have 2 servers which are the same spec ie box, processor etc. The
only difference I can tell is that the production box has raid setup
but the test box hasn't (I think).
I have created a stored procedure to insert 10k rows into a dummy table
with two columns.

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...

To those that have been around Access long enough, I'm sure that
insight can be shared as to what aspects of computer processing speed
improves its performance. Perhaps in some respects even sufficient to
partially offset an inadequate or poor database design. Also, and using
Access 97 as a starting point, have there been significant
changes/improvements in performance of the later versions of Access?
Assuming that a system has adequate...

Hi,
I'm currently developing an application that uses a lot of
computational power, disk access and memory caching (to be more exact:
an information retrieval platform). In these kind of applications the
last thing that remains is bare performance tuning.
So for example, you can do an 'if then else' on a bit like a 'case/
switch', an 'if/then/else' and as a multiplication with a static
buffer. Or, you can do sorting with an inline...

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.
