Define "small" ;) There a certainly patterns that cannot/will-not take advantage of SG (for instance, your typical network rx path), and therefore the sg entries are wasted in some cases. Since they need to be (IMHO) u64, they suck down at least 8 bytes a piece. Because of this I elected to use the model of one pointer per descriptor, with an external descriptor for SG. What are your thoughts on this? -Greg ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
