Hi,
We ran MySQL (4.0.15-standard, 64-bit, SuSe 8.0) benchmarks
on 2 CPU and 4 CPU Opteron machines. Mostly we tested insertion
times with many simultaneous connections (hundreds). To our
surprise we did not find significant differences.
Each of our servers (2 and 4 CPU machine) has one 1Gbit network
connection. I have feelings that the machines are the network
bounded, not the CPU bounded. Could it be true? How to verify it?

Hi guys,
We have a problem with Dual AMD64 Opteron/MySQL 4.0.18/Mandrake 10
for a very high volume site. We are evaluating the performance on our
new server AMD64 and it seems it's slow compared to Dual Xeon/MySQL
4.0.15/RedHat8 and Dual Xeon/MySQL 4.0.18/Mandrake 10.
And it seems there are zombie threads. 570 threads in 1 hour and we
didn't even use JDBC connection pooling at all. These threads are
supposed to be gone within 60...

Does anyone have any information about 64 bit python support for Xeon
and Opteron architectures on Windows platforms? If anyone has built the
python runtime on either of these platforms before I would be really
interested. Thanks.

Hi,
We're thinking of moving to a 64 bit platform for our database. Does
anyone have any stories of migration from 32 bit to 64 bits?
* How did it impact performance?
* Were there any gochas?
* What processors were used (any AMD Opteron's so far?)
Also what kind of performance increase could we expect if we moved from
a dual 32 bit to a quad 32 bit platform. (We are already using speedy

Hi all,
at the company where I work, we're planning on installing DB2 on an AMD
Opteron with 32GB of memory.
Let's say we're running DB2 8.1 FP 7 in 64bit mode on SuSE Linux
Enterprise Server 9.0. Can we create bufferpools with a size over
4GB? Let's say 12GB?
Has anyone got any experience running such a configuration?

Hello all,
I was wondering what's best for PG, since we have to
decide what will be the new server for our DB, that
will serve one or more websites.
Our actual configuration is a dual xeon 2.8ghz with
4Gb ram + scsi disks, and works fine, though some
intensive insert/update processes has taken it to 100%
cpu use.

Hi,
I have been seeing a strange behaviour when doing some tests on a Dual -
Dual Core Opteron system using Windows XP (32bits with SP2).
In out application we have a wrapper around the thread pool to handle the
work on renderers and CPU intensive tasks. On the Dual - Dual Core Opteron,
the application is correctly starting 4 threads but it seems to be running
only 2 concurrently.

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:

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,...
