Matt, Interesting stuff. Did you test copying of the recordings on the ramdisk to a local harddisk also during that 512 call load? Just wondering if that copy action wouldn't also create an I/O bottleneck and cause call quality issues under load. Did you consider using remote storage e.g. via nfs, a fibre channel or iSCSI link to a SAN?
