postgresql queries on droplet slow with respect to same queries on local laptop
I have a postgresql server 11.2 running as a container on a 4GB, 2vCPU, 80GB droplet.
/proc/infoshows: cpu MHz=2399.998, bogomips=4799.99.
No other activities on the droplet, apart from this.
The same postgresql instance is running on my laptop, a MacBookPro (Retina, 13-inch, Early 2015, 2 cores, 2.9 GHz Intel Core i5).
An exact dump of the remote droplet DB has been restored locally on the mac.
Queries on the mac take consistently far less time (5x) than on the remote DO droplet:
What could be a possible cause?
