[Linux]ROOT6 very slow startup

SJLPHI · September 21, 2016, 2:23pm

Hello,

I have been using ROOT 5.* for some time, and I have been told to use ROOT6. I deleted ROOT5(make clean, then remove recursively of the old ROOT directory).

My kernel is:
4.7.2-2.g8a962cf-default
64 bit, OpenSUSE 13.2 OS
My root configuration is:
./configure linuxx8664gcc --enable-minuit2 --enable-roofit --enable-table --enable-gdml --enable-pgsql --enable-mysql --enable-builtin-zlib --enable-builtin-pcre --enable-builtin-freetype --enable-builtin-glew --enable-afs --enable-soversion --enable-rpath --enable-opengl --enable-pythia6

The startup time in ROOT5 was instantaneous, with ROOT 6, startup time is over 10 seconds. The strange part is also that the startup on ROOT6 is much faster, when I am at home network, instead of work network.

I would appreciate any help. Thank you.

Try to play with:
root -b -n
and:
root -l -n

SJLPHI · September 21, 2016, 2:31pm

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’

Pepe_Le_Pew · September 21, 2016, 2:38pm

Why do you get the “Welcome …”?

SJLPHI · September 21, 2016, 2:40pm

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

SJLPHI · September 21, 2016, 2:41pm

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

Pepe_Le_Pew · September 21, 2016, 2:42pm

Not for me.

SJLPHI · September 21, 2016, 2:46pm

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

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.

Pepe_Le_Pew · September 21, 2016, 7:12pm

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

SJLPHI · September 21, 2016, 7:26pm

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

No change.

Pepe_Le_Pew · September 21, 2016, 7:32pm

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”)?

SJLPHI · September 21, 2016, 7:37pm

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

Pepe_Le_Pew · September 21, 2016, 7:42pm

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

SJLPHI · September 21, 2016, 8:17pm

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.

SJLPHI · September 21, 2016, 9:01pm

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

SJLPHI · September 21, 2016, 9:38pm

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.

p73 · September 26, 2016, 4:23am

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.
