Furthermore, Flash memory has a limited lifetime regarding to erase/write cycles, usually in the range of 10,000 - 100,000 cycles. So, using flash as swap is a quite stupid idea, unless you're ok with the degraded performance and the costs of buying a new device every few weeks. /Ernst _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
