<div>Yes, it's an issue if there is a large subnet (performance issues due to broadcast as well as resource issues due to number of MACs on the subnet, etc. - the severity would depend on the scale+size). Or use L3 agents/ overlay / etc. - which may have its
own performance issues depending on your scale.</div></div></blockquote></div><br></div><div class="gmail_extra">Hi Manish,<br><br></div><div class="gmail_extra">Do you have a number of just how big a subnet size is when it starts to have negative impact on the performance of the subnet?<br>
<br></div><div class="gmail_extra">How would you benchmark network performance? Booting many VMs with significant network load is not possible since I don't have enough hardware. Is there a way to simulate and investigate the issue?<br>
