XenApp 6.5 on VSphere 5->Vm performance issue

Hi all,

I am having some perfs issues with Vm (Win 2008 R2, 4 GB Ram, 1 vcpu and XenApp 6.5) and I am wondering if that could be a datastore issue because we are using datastore clusters.

Has someone set up a XenApp 6.5  virtualized on VSphere 5 ?

Thank you

Regards

Bernard
