Re: Seeking Insights on Choosing the Right CPU and RAM for PostgreSQL Setup

Hi Muhammad,

Yes, the previous email was generic without specific details. However, I would appreciate guidance on sizing based on the following specifics:

1. Database size: Approximately 5TB.

2. Current TPS (Transactions Per Second): 1000-1500 TPS.

3. Read-write ratio: 60-40%.

4. Configuration: It’s a three-node setup.

5. Concurrent users: Typically between 300-350.

Hi Veerendra,

It depends on your database size, kind of queries, concurrent users etc. BTW, your question is too generic.

Dear PostgreSQL Community,

I hope you’re all doing well. We’re currently evaluating hardware options for our PostgreSQL setup, specifically focusing on CPU and RAM. We’d love to hear your insights on the following:

CPU:

• Optimal number of cores?
• Impact of clock speed?
• Preferred CPU architectures?

RAM:

• Recommended amount?
• Importance of memory bandwidth?
• Buffer cache configuration tips?

Any advice or experiences you can share would be greatly appreciated. Your input will help us make informed decisions and optimize our setup.

Thank you!
