MAINWP and 27 child sites on the same VPS server. When I click Sync Dashboard with Child Sites the RAM consumption spikes. If I do it at the same time as other processes such as SPAMD it brings the websites down.
There are numerous php-fpm: pool processes running after clicking the Sync Dashboard with Child Sites and they each take up RAM resources. After the sync is done RAM usage goes back to roughly 50%

Web hosting company says I need to pay for a bigger VPS but the cost difference it too much to justify.
Can I make this work on my current VPS or should I put the MAINWP website on a separate server?
