I could not reproduce this by using my boxes after all, but replacing pxeboot with the older one was useful to gain the normal speed at that time probably because of difference between new (11 or later) loader's nfs client and the old one. It was a problem sending a lot of duplicated packets for some reason, not just a matter of the buffer size. And the server side was Linux. Have anyone else also experienced this kind of very slow PXE booting? It may be specific to using a Linux NFS server. -- Hiroki ----Security_Multipart(Wed_Feb_26_05_57_17_2020_667)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- iMgEABMKAC4WIQRsDSNTJ8+Ax5Ae/dLbsH3Gbx9zfwUCXlWKLRAcaHJzQGZyZWVi c2Qub3JnAAoJENuwfcZvH3N//DsCBRdZFB7RWqFIIlOPxpSPD24nVonY9Eix7rnU eqc7P2hi/huVcd23j40lZmUKqAbNGcL5Saincu05iM+lDi+G+ipGAgdN/8xnx/zO yNgnbIbeODPZgsRVB4hn2rw+6uOwv3ABHd5kUzMO3te2RiY2OQqi+yVxtmmYzjMl fLvXRZ64KTf9Jg== =ijW3 -----END PGP SIGNATURE----- ----Security_Multipart(Wed_Feb_26_05_57_17_2020_667)----
