Slow performance when booting into PXE Windows PE to image devices

Just wondering if anybody has encountered a similar issue where booting into PXE takes over 40 minutes? We are running XGS1930-52HP with 10Gb links and 10Gb links back to the server. Tried direct to the server via a USB Network card bypassing the switches, and we do not get the issues, so cleary a switch problem?

    I understand that what I'm gonna write is maybe something you already looked for...

    1: does your PXE image correctly detect and configure the network card for the maximum performances?
    2: you had any other image of OSes (so not only Windows PE) as test?
    3: How it's configured currently your XGS1920-52HP?

    Hi @Alamo

    Welcome to Zyxel community!
    Since some PXE will use multicast to send OS to the client PC, may I know what PXE software do you use, and do you limit the multicast storm with storm control? 
    Could you share your configuration here or PM me for better clarification?

    A1- The network card is auto-configured as standard there is no config for this.
    A2 - We have not tried to PXE boot other OS but bypassing the switches works, so rules this out.
    A3 - Unsure what config you want me to provide; there is no config on the switches specific to PXE; your questions seem very vague and not related to the issue.

    We currently use WDS for PXE booting, where is the storm control setting on the switches?

    Hi @Alamo,

    I assume your XGS1930-52HP is using the standalone mode, please go to Menu > Advanced Application > Broadcast Storm Control to check. If it is enabled, please disable it and try again.
    The below screenshot is an example for enable multicast control.

    We are using the Nebula cloud, is there something similar on there?

    These are the switch port options and Storm Control looks to be disabled.
