It's an implementation of the Linux ABI on top of Windows service(s). If you told me that they build some of it from actual Linux kernel sources, I'd believe you. (Rather like User-Mode-Linux) If you told me that they have a kernel that they build for when they actually spin up an actual VM (such as to run containers) that would also be unsurprising. > ... > CONFIG_NET_SCH_DEFAULT=y > CONFIG_DEFAULT_FQ_CODEL=y > # CONFIG_DEFAULT_PFIFO_FAST is not set > CONFIG_DEFAULT_NET_SCH="fq_codel" It would be nice if the billion windows desktops started doing something better, but I don't think it will help observed latency. The real question is what the default schedule for the default Azure Linux VM is. --=-=-= Content-Type: text/plain Content-Disposition: inline Content-Description: Signature -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | IoT architect [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails [ --=-=-=-- --==-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQFFBAEBCgAvFiEEbsyLEzg/qUTA43uogItw+93Q3WUFAmP6cW4RHG1jckBzYW5k ZWxtYW4uY2EACgkQgItw+93Q3WUxvAf/WCXTUueJRtGI1ioKPYPTJzKyWA9xZzHU TMGITYEDe/OuGPqr6zdWrivQWvelfLwpaj3C2Rrs0+KYQqLdTxzOwUrilxkjC9E1 Jd0OWamF58W4M3I3t44E+7OlPeaomQzU5bu11YUdrbEy7KKuUrVxshFLBHoleo5g 1a8ROBMo/Nw3d+LXjtmIfvv6qxx8IdKCCIvPXTK9r5JmjRUuuHBpQbf3u+DW3mMg uc6vvQZkMITgsbkiHkcGH46P/w9U/j/Q3UDCLRBxyFGWDktq4SpyY4Dih3UXGnmC qAtAHrq05TREELU/u/vi0yiTH+xaz9oLUEX33dAvInLSiwS1QTfskg== =5zEJ -----END PGP SIGNATURE----- --==-=-=--
