[Linux]ROOT6 very slow startup

ROOT

Hello, thank you for the quick reply.
They are about the same. If anything, batchmode is slightly slower.

More specifically:

[code]SJL@Gyro:~> time root -b -n -q;time root -l -n -q

Try ‘.help’, ‘.demo’, ‘.license’, ‘.credits’, ‘.quit’/’.q’

Why do you get the “Welcome …”?

ROOT5 time, on a bad day.

$ time root -b -n -q; time root -l -n -q root [0] real 0m0.347s user 0m0.246s sys 0m0.105s root [0] real 0m0.344s user 0m0.259s sys 0m0.088s

7

batchmode still outputs the bash welcome ‘graphics’, at least for root6

8

Not for me.

It’s a surprise for me also, ROOT 6.06 which is what we’re asked to use for the time being shows it.

.bashrc and .rootrc

[code]SJL@Gyro:~> bashme |grep -i root; dog .rootrc;

Try (make sure that all libraries, which are not “standard”, come from your new ROOT 6 version):
ldd which root
ldd which root.exe

I’m not quite sure what I am looking for here.

12

Try (here, in the first call, I get the “Welcome …” logo):
time root.exe -b -n -q; time root.exe -l -n -q

13

[code]SJL@Gyro:~> time root.exe -b -n -q; time root.exe -l -n -q

No change.

14

Can it be that in your PATH or LD_LIBRARY_PATH you have some “external” (e.g. “NFS”, or “AFS” mounted) subdirectories which do not exist (e.g. the corresponding server is “down”)?

15

Actually, possibly, I will re-compile ROOT, with least number of necessary packages.

16

I’ve seen numerous reports that ROOT 6 has problems with “configure”, so try the “cmake” method, e.g.: Trouble compiling ROOT 6

17

Progress:
offline, or home network, startup time is ~0.2 seconds.

./configure linuxx8664gcc --enable-minuit2 --enable-roofit --enable-table --enable-gdml --enable-builtin-zlib --enable-builtin-pcre --enable-builtin-freetype --enable-builtin-glew --enable-soversion --enable-rpath --enable-opengl --enable-pythia6

work network, still >15 seconds.

18

I’m starting to get very curious, what is accessing the network/internet from root?!

19

I found a solution:
sft.its.cern.ch/jira/browse/ROOT-6912

Similar methods to Mac,

in
/etc/hosts
I’ve added a line
127.0.0.1 $HOSTNAME
Everything is now working in good speed.

I should also update, that the configuration file for me works, and none of the enabled packages were causing the problem.

I begin root session with root -l but it print ROOT LOGO first. The same thing with root -q and etc.
More over, If I try root filename.root , it does not work and just run root as usual.
Please help.

Thanks in advance.

I’ve had this issue for many years. I’m glad someone has finally traced it down.
