GTM eDNS request

in the end, we updated the irule to when DNS_REQUEST { set ldns [IP::client_addr] if { ([string tolower [DNS::question name]] equals "x.x.x.com")} { if { [DNS::edns0 exists] &! [catch { DNS::edns0 subnet address }] } { set gtm_ecs_address [DNS::edns0 subnet address] set gtm_ecs_source [DNS::edns0 subnet source] set gtm_ecs_scope [DNS::edns0 subnet scope] set ldns $gtm_ecs_address if {([class match $gtm_ecs_address equals condicion_A])}{ DNS::answer insert "[DNS::question name]. 10 [DNS::question class] [DNS::question type] 1.1.0.1" DNS::return } else { DNS::answer insert "[DNS::question name]. 10 [DNS::question class] [DNS::question type] 1.2.0.1" DNS::return } } } }

we feel like there is a feeling of slowness, can yhou confirm if normal behavior
