Hi all: I'm trying to make a VM filesystem benchmark of XCP 1.0 using NFS with local caching enabled and disabled. I'm using iozone. My infrastructure is configured as above: Storage: NetAPP - NFSv3 - 4x gbit ethernet aggregated with Jumbo Frame enabled. All switches have 10 gbit/s port link and have Jumbo frame enabled in all ports Servers: blade HP with 10 gbit ethernet - Nehalem processors model L5640 (2 x 6 cores with Hyper-Threading) - 24GB RAM The problem: I've 8 gbit/s to write and I think the host is making cache. It's unfeasible my tests. The iozone is running over a CentOS 5.4 64bit. Thoughts? -- Marco Sinhoreli _______________________________________________ xen-api mailing list xen-api@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/mailman/listinfo/xen-api |
