[development] Drupal 5.1 on RHEL5 - virtualized

[Jakub Suchy]

Hi,
this is not too much useful, but maybe interesting:
I am trying Red Hat Enterprise Linux 5 Server now and tried to install
one virtualized host and benchmarked Drupal 5.1 running on Domain 0 vs.
Virtualized host.

The hardware is: Intel Celeron 2.8GHz, 1x 80GB IDE HDD, 1.5GB RAM
Domain 0 is  default installation, limited to 500MB RAM in
grub
Virtualized host is default installation, limited to 500MB RAM by XEN

I installed PHP 5.1.4, Apache 2.2.3, MySQL 5.0.22 and Drupal 5.1 with
2000 nodes and 2000 comments on both.

The results are:
