I'm experiencing the same script to run faster on rstudio 1.2.5033 than in 1.4.1106. It seems related to the former using all the threads in the CPU while the latter only one. I'm working in a Linux Mint 20 environment of two highly similar, albeit different, machines with the same 5.4 kernel. I am not an expert and I do not understand what is going on.
Can anyone please point me to the right documentation to better understand this different behavior?
Thanks in advance
