If it's such a big performance hit, you could create a separate virtual server for the pilot subnets and not use an iRule on either virtual server. Else, you could optimize the iRule slightly by removing the debugging altogether: 


when HTTP_REQUEST {
   if { [matchclass [IP::client_addr] equals Pilot_Subnets] } {
      if { [HTTP::header "User-Agent"] contains "mozycorp-windows/1.8" } {
         pool HTTP-PROXY_80 member 3.56.142.241 80
      } else {
         pool HTTP-PROXY-IRONPORT
      }
   } else {
      pool HTTP-PROXY_80 
   }
}
