Fundamentally ... the real issue is that large numbers of smart people have spent a lot of time tuning TCP on various platforms for more than a decade. In that same time, Rx has received very little attention. I was able to fill a Gig-E pipe with RxTCP with relatively little work (by "little" work I mean tuning I did to RxTCP - RxTCP ended up being a lot of work). All that I need to do now is finish the damn thing and get it working in real clients and servers. Hopefully soon. --Ken _______________________________________________ OpenAFS-devel mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-devel
