I wanted to see how fast mongodb is before I started using it. So I wrote a small test to take an apache log and dump it into a mongodb database. I wrote everything in C++ to see how fast I could get it and here are my results:
I use my Profiler.h program to profile just the execution of reading the file and inserting into the mongodb. Here is my output and you can see I achieved ~19 million inserts in less than 5 min. Would love to see your results.
