I use the “built in” benchmark pgbench to run a simple set of queries. pgbench creates a ~7.4gb database using a scale-factor of 500. Then reboot the kernel I used these excellent resources How to modify the kernel command line How to enable hugepages and this great video on Linux virtual memory. Experiment.

Video Transcoding. Chokepoint : Even sharded Berkeley DB was choking under the stress and there was a database crash with recovery taking hours, it had to be replaced. We already use the public cloud to autoscale some async processing like Video Transcoding, text extraction, data migration, Search, etc. Document store.
