Hi Mark and Jea, thank for posting and sharing.
The team at Mellanox is continuously working with VMware to improve the performance and user experience with the VMware and alike environment, we are planning on improving iSER as well. I do not have any timeline but at some point we will introduce improvements. Having said that, iSER performance is superior to IPoIB and among the available options it is still leading. from this point it can only improve
Thanks,
