Re: [ovirt-devel] [VDSM] Profiling results - 144 cores, 144 vms

----- Original Message ----- Let's look at DomainDescriptor's __init__ class DomainDescriptor(object): def __init__(self, xmlStr): self._xml = xmlStr self._dom = xml.dom.minidom.parseString(xmlStr) self._devices = self._first_element_by_tag_name('devices') self._devices_hash = hash(self._devices.toxml() if self._devices is not None else '') so we parse using the slow minidom _and_ we do toxml() on a subset of the xml tree. Both operations are expensive (and quite memory expensive). Milan is already working on moving from minidom to etree, I think we are on good track here for 4.0. -- Francesco Romani RedHat Engineering Virtualization R & D Phone: 8261328 IRC: fromani
