my openvpn client and server are in local network, use a cable connect client to server.
Client
tun2: inet addr:100.8.0.6 P-t-P:100.8.0.5 Mask:255.255.255.255
Server
tun0: inet addr:100.8.0.1 P-t-P:100.8.0.2 Mask:255.255.255.255
when ping from client to server virtual IP(tun0) 100.8.0.1:

every 5 packet, appear a packet with big delay..
if I ping the listened ip by server from client , no delay at all .:

client vpn version is the same as the server : both is OpenVPN 2.0.9. even if I change the server version to 2.3.x ,the delay still appear.
