[SR-Users] SQlite in memory

[Ovidiu Sas]

Do you use a lot of logging?
Have you enabled asynchronous logging?

If you are using the DB only for dispatcher, then you have other
issues then the db. The dispatcher module is caching the data on
memory.

You can do hundreds of CPS with only two workers and the CPU will be
at 3% utilization on very old hardware.
There's something else in your config creating issues.

Ovidiu Sas
