Request/response pairs are serialised in the C xenstored. Further, multiple in-flight transactions are allowed (although the rather basic conflict detection means that all but the first to commit will be failed). We might move to a smarter xenstored, but overall higher parallel performance of one domain's xenbus implementation is probably not a very important thing to optimise? -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
