APIv2: /info is getting slower

[edsantiago]

The "ten /info requests" timing test is getting slower:

podman/test/apiv2/01-basic.at

Lines 62 to 78 in 3668211

	# Timing: make sure server stays responsive
	t0=$SECONDS
	for i in $(seq 1 10); do
	# FIXME: someday: refactor t(), separate out the 'curl' logic so we
	# can call it directly. Then we won't get ten annoying 'ok' lines.
	t GET info 200
	done
	t1=$SECONDS
	delta_t=$((t1 - t2))
	# Desired number of seconds in which we expect to run.
	want=7
	if [ $delta_t -le $want ]; then
	_show_ok 1 "Time for ten /info requests ($delta_t seconds) <= ${want}s"
	else
	_show_ok 0 "Time for ten /info requests" "<= $want seconds" "$delta_t seconds"
	fi

It was bumped up from 5 to 7 seconds last week, and is about to get bumped up to 10 (#8065) because it is causing CI flakes:

• PR System tests: remove some misleading 'run's #8061
  • 10-19 11:24
  • 10-19 11:07
  • 10-19 11:01
• PR Always add the dnsname plugin to the config for rootless #8044
  • 10-17 09:41
• PR Fix indentation for podman pod inspect #8021
  • 10-14 14:10
• PR Fix missing OCI Runtime #7126
  • 10-20 10:07
  • 10-20 09:38

This issue is a placeholder so the slowdown can be investigated and, perhaps, addressed.

Closing do to lack of activity.
