Root slow at startup when connected to the internet

ROOT
1

Hi,

I’ve noticed that if I’m connected to the internet, root takes a significantly longer time to start. I’ve noticed this only now that I’m travelling abroad…

Below is the output of “time root”, after quitting right away, when I have my airport turned off (it takes ~4 secs to start up) and when I have my airport turned on (~32 secs to startup)

I’m using root 5.13/02 on a mac OSX 10.4.11

Any ideas why this might be ?

Thanks!

Nicolas.

When starting root with “root” the splash screen is shown and this requires the X11 server to contact your name server.
Coukld you repeat the same operation with

time root -l -q or

time root.exe -q or

time root -b -q
On my MAC each of the 3 commands above take 0.6 seconds where

time root -q takes 4 seconds

Hi,

I still get a slow startup even when running in batch mode, and it’s much faster when I turn off the airport. Below are the outputs of each command.

With the airport on it took 36 secs for root -l -q and 30 secs for root -b -q, and 1 sec and 0.7 sec respectively with the airport off…

Could you try with a recent version of ROOT?

Cheers, Fons.

Hi,

with root 5.14 I don’t have this problem.

Thanks!
