RouterOS PPTP Server with multicore cpu

Hello!
We try to test RouterOS 5.14 as PPTP Server on WMVare ESXi 5
Virtual machine has 2 cores, 256M memory, gigabit ethernet virtual network adapter
Two clients connect to server and one downloads file from other.
We see hi utilization first core, but second core has 0% utilization.
Can pptp server work on two and more cores?
