ネットワークドライブへのアクセスが遅いときの対処法

Last updated at Posted at 2013-06-07

Mac(特にMacBookAir)でネットワークドライブ(共有フォルダ?)へのアクセスが激しく重い場合、

# sysctl -w net.inet.tcp.delayed_ack=0
net.inet.tcp.delayed_ack: 3 -> 0

とすると解決。デフォルトは
このままだと当然ながら再起動したときに戻っちゃうので

/etc/sysctl.conf(/private/etc/sysctl.conf)
net.inet.tcp.delayed_ack=0

これも忘れずに。
OSXはsysctl.confがないので新規でつくろう。
