  • *Abstract : *

  • In the proposal, I would like to share how we have optimized a few database parameters that did outburst the performance by several times. It was a PostgreSQL Server of size 325 GB and more than 1500 TPS. After our tuning, we were able to get the database process upto 4900 TPS without compromising on ACID or availability.

  • ** The talk includes : **

    • The environment where we have seen disastrous performance.
    • The parameters we concentrated for tuning and why ?
    • The way we analyzed the active data set and optimized many more parameters in run time
    • Answers to questions like :
    • Does my active data set fits in memory ?
    • Should I increase work_mem ?
    • Is WAL compression working to my advantage ?
    • How far should I have checkpoints spread ?
    • By the end of this talk, you should know what parameters you should tune in PostgreSQL and when.
