Slow TFTP File Transfer in Uboot 2020

I've got a tftp server running on a virtual machine host, and I'm trying to tftp a linux kernel onto a TI AM33 processor. Both devices are connected on the same network switch. I'm noticing that TFTP is much slower on uboot 2020 compared to uboot 2013. My uboot 2013 has a transfer time of ~14 seconds, and 2020 has a transfer time of 5 minutes. Is there something in the configuration that I can change. I have set TFTP_BLOCKSIZE to 1464 and TFTP_WINDOWSIZE I've tried values between 1-16. Are there variables in the UDP stack that it would be good to check? This is a picture of wireshark for the device. I was wondering if the response time seems quick enough as well? In wireshark I'm seeing an average response time of .00043 seconds Is that slow for TFTP?
