Proposal
Default value for max_samples_per_send - 100 - is too low for any non-idle Prometheus setup with remote_write enabled. It results in too frequent requests to remote storage if Prometheus scrapes more than a few hundred metrics per second. High requests' frequency wastes resources on both Prometheus and remote storage sides, so users have to increase max_samples_per_send after the first attempt to write metrics to remote storage.
It would be great if default value for max_samples_per_send is increased from 100 to 1000 or even 10K. This would simplify remote_write configuration for the majority of users.
