For RAM requirement please look into this:<br>
<a href="https://www.pgpool.net/docs/latest/en/html/resource-requiremente.html" rel="noreferrer noreferrer" target="_blank">https://www.pgpool.net/docs/latest/en/html/resource-requiremente.html</a><br>
<br>
CPU requirement is not in the document because it's heavily depending<br>
on the application usage. i.e. how much data is transfer ed and how<br>
frequently data is transfer ed. If they are much and frequent, CPU will<br>
be busy and you would need many cores. From my personal experience, 4<br>
cores would be a good starting point.<br>
<br>
Best regards,<br>
