When we have about 15 users logged in (mostly POS Users), ERPNext becomes slow. Trying to open anything takes time and the screen Grey’s out for a while as though the system is busy with something… and this happens even during intervals when no sales are getting synced (we use offline POS)
This is happening on an AWS server with 16G RAM and 4 CPUs. There’s enough free RAM and Innodb Buffer Pool size is set to 8GB
What could be the issue and how do we improve this?
Also, do sales coming in from Offline POS transactions get handled as background jobs? If not, shouldn’t they?
