Tuning the OCaml memory allocator for large data processing jobsPublished on Saturday, June 19, 2010 and tagged with programming, ocaml, and performance. TL;DR: setting OCAMLRUNPARAM=s=4M,i=32M,o=150 can make your OCaml programs run faster. Read on for details and how to see if the garbage collector is thrashing and thereby slowing down your program. In my research work with GroupLens, I do a most of my coding for data processing, algorithm implementation, etc
