I think there’s some housekeeping missing after installation. I installed via mapd.com/download using Ubuntu x64 > apt instructions. I skipped messing with sample data and went straight to loading my data. It loaded at a rate of about 5900 records per second second. After performing a query to test it out, my next table loaded at over 1 million records per second and I’ve had no issues with slow loading ever since.
Seems like there’s some housekeeping that didn’t get done until I ran the sample query. Just wanted to give a heads up, thanks for an amazing engine!
