Question about MySQL performance on 2 and 4 CPU Opteron machines

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?

Thank you,

Jacob Nikom

MS SQL is simply not an option for us at this time and the site is getting enough traffic that Access's 10 concurrent connection limitation...

Hello, I am having this problem that is just driving me crazy.. When using Bugzilla with Mysql (all Mysql, Perl, and modules all supplied by RedHat for RHEL 3.0), MYSQL hangs frequently.

I have also downloaded the pre-built binaries for MySQL AMD-64 from the MySQL website. Now CPAN...

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...

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,...
