I built a new workspace using a different platform and ROOT version.
New OS is Window [Previous was OS x]
I used ‘Hyper TM’.
I installed wsl with Ubuntu newest version and ROOT also successfully installed.
but When I sourced ROOT and entered ‘root -l’, the opening speed is too slow.
[ Some calculation or other processing is work well tho]
@Axel Yes. I installed ROOT on my local disk.
disk speed is roughly 460 MB/s for read and 380 MB/s for write. (I checked this by winsat)
and output of time root.exe -l -q is real 0m15.190s user 0m0.245s sys 0m1.915s
Is the problem only seen with ROOT? Is anything else fast to open? e.g. xeyes, xcalc, python,… maybe try installing a few other ‘graphical’ apps and see if they load slowly too (in which case it would probably not be a ROOT issue, and you could try reinstalling Ubuntu, even WSL too, to start from scratch).
@dastudillo Hi ! I think the problem only seen with ROOT. I’m currently using python3.9 and other ‘graphical’ app (e.g matplot, seaborn, so on) as well. but the loading of some images by Python script is showing up very quickly. Actually, ROOT loading speed itself is too slow. the processing (Tree read & write, function fitting) seems no problem.
First part was done very quickly. so I could see the path of ROOT immediately.
Below is the result of second the thrid command.
:$ time root.exe -l -q ; time root.exe -l -q ; time root.exe -l -q
:$ time root.exe -b -l -q ; time root.exe -b -l -q ; time root.exe -b -l -q
