I would try the "track" option:
backend tester
bind-process 1
server one1 ... check
server two2 ... check
backend BE1
bind-process 1
server one1 ... track tester/one1
server two2 ... track tester/two2
backend BE2
bind-process 1
server one1 ... track tester/one1
server two2 ... track tester/two2
The suggestion in
http://cbonte.github.io/haproxy-dconv/1.9/management.html#7 "...it
appears that the easiest setup often consists in having one first layer
running on multiple processes and in charge for the heavy processing,
passing the traffic to a second layer running in a single process." may
further help in reducing the number of "backend processes" and
consequently the number of checks.
