Is the data given in RAM or do you have to wait for spinning rust I/0 for some GB amount of data?
- londons_explore 3y agoThe test procedure is to run the code 5 times. Even if it isn't in cache the first time, it will be in the OS cache (ie. RAM) for the 2nd-5th runs. The test machine has 32GB RAM, while the data file is only 12GB, so it ought to be fully cached.
