MongoDB data migration
07/07/2015
Here is some benchmarking data regarding transferring data from one machine to another. These benchmarks were run on the AWS i2 instance class.
- mongodump – 15min / 100GB
- gzip using pigz – 15min/100GB
- network transfer – 20min/100GB
- extract archive – 30min/100GB
- mongorestore -j 12 – 2hr/100GB
should be much faster to directly copy the data files over UDP
