Hi! I have a .csv file of geophysical points data (x,y,z, resistivity), each file has 15 million rows. I was trying to make a numerical model but it takes a long time. What other option would help me to process this information in a more efficient way.

PS1: my computer has 128 gb RAM memory.
PS2: Before the information was only one file of 75 million rows, which was subdivided into three files, and information was filtered until it reached 15 million rows.
