Am I right in assuming that you're establishing application-layer sessions to
two hosts with two different IP addresses (outside of your control) which
provide (close to) identical services? If so, there's not much you can do
outside of the application itself (at least if you want a semi-robust
Anycast?

Might need to know a little more about the layout here for a better answer.

Maybe I am missing something, but how does VRRP/HSRP cause latency?

VRRP/HSRP does not cause latency the problem we faced prior was when links
flapped or timed out this would be too much of a hindrance for our users to
reconcile application state with various trading venues we are trading
thousands upon thousands of trades a minute to various destinations.
As
HSRP/VRRP can be tweaked to less than 1s fail over time. Can you provide
a copy of your network map for analysis? GLBP might be a viable option
as fail over is not actually an issue at that point.
