I have receiced a problem from my customer about high ping delay of HP 1910-24G. If i ping another network device through the switch, the delay will be less than 1ms. But if i ping directly to the switch, the delay is equal to 1ms or higher. This problem is the same with HP 2520 series witth latest firmware, so i think is this a firmware problem or because of hp switching 's architecture
This problem doesn't present on Cisco Switch thought
