I’ve been constantly plagued with slow network transfer times during maintenance windows on FreeBSD based Junos installs, but didn’t think much of it assuming it was just due to slow flash.
It’s apparently partially a little bit of column A and a little bit of TCP tuning and there’s an apparent workaround:
start shell user root
sysctl net.inet.tcp.sendspace=2048000
sysctl net.inet.tcp.recvspace=2048000
kill `ps aux | grep inetd | grep sbin | awk '{ print $1 }'`
I haven’t had a chance to try this personally, but if it works, this would be huge. People tell me this doesn’t apply to EVO and it may not work at all if the flash itself can’t support the speed, so try at your own risk.
