Exactly.  A few years ago I migrated a company's virtual systems from 
VMWare (slow) to OpenVZ (fast).  Most of the systems were running Tomcat 
for development.

OpenVZ applies strict resource constraints[1] to prevent containers (CTs) 
trampling on one another.  These were a precursor to cgroups that are now 
integrated in to the kernel.

During testing we found that Tomcat wouldn't start on a CTs with low 
memory constraints.  We found that Tomcat was asking for but never using 
enormous amounts of ram.  After tuning down the initial resource 
requirements of Tomcat it ran just fine under OpenVZ.  OpenVZ was used at 
this company for years and, afaik, still is.

I have the same browser resource issues that others are mentioning of 
course.  Maybe it is time to apply for cgroups

Hmm I wonder what would happen if I got cgroups to limit the brower's 
resource consumption.  Apps are going to have to get better at living in 
an environment in which the OS says 'no' to resource requests more often.

[1] Most problems people report with OpenVZ come from misunderstanding the 
resource limits.  The key I found was to avoid hand tuning (while well 
documented this is a difficult and thankless process) and get 'vzsplit' to 
do the hard work.

Cheers,

Rob
