This is happening only in post-install operation -- single user as well as multi-user mode. During installation (which was done in ftp mode using an ftp server on local ethernet), the performance was normal (about 400 Kbps ftp transfers). A tcpdump shows that FTP transfers a chunk of data, waits for *two seconds*, then transfers a chunk ... and so on. 16:36:48.167449 elbereth.40051 > kchowksey.ftp-data: . ack 12960 win 17280 (DF) [tos 0x8] 16:36:48.167599 elbereth.40051 > kchowksey.ftp-data: . ack 12960 win 17280 (DF) [tos 0x8] 16:36:49.641186 kchowksey.ftp-data > elbereth.40051: . 12960:14400(1440) ack 1 win 17280 (DF) [tos 0x8] 16:36:49.644203 elbereth.40051 > kchowksey.ftp-data: . ack 17280 win 12960 (DF) [tos 0x8] 16:36:49.644353 elbereth.40051 > kchowksey.ftp-data: . ack 17280 win 17280 (DF) [tos 0x8] Does any one know what could be happening here ? -- Kapil Chowksey kchowksey@hss.hns.com
