Fwd: Caché com VMware

March 11, 2007 InterSystems Products and VMware Virtualization Software

InterSystems has determined in benchmark and customer testing that VMware
environments running Caché and Ensemble require significantly greater CPU
capacity than native installations on the same hardware. In multi-user
tests, CPU load is typically twice as great (200%) of the same tests run on
the same operating system natively (i.e. without VMware) on the same
hardware. Additionally, there are application specific implications for
response time for interactive jobs.
InterSystems, along with a number of its customers, have reported this
problem to VMware and VMware is investigating. For updates on the status,
please contact VMware Global Alliance team.
This affects all versions of all InterSystems products. Until a solution is
available from VMware, InterSystems recommends that any customers
contemplating a VMware deployment
·       Ensure that available CPU capacity is at least twice as large as a
native installation and
·       Conduct application specific testing to ascertain what, if any,
response time impact will be noticed by users.
