Slow transfer speeds

shakisha

I have got an openvpn server, version 2.3.10 on a centos 6 server, and i'm getting transfer speeds around 200-300kbit from both windows and mac clients.

I've made the tests with this environment:

.2HTTP machine
.1 vpn server

.10 connected client

nload on .2 give me 36mbit/s outgoing

but on .10 i receive only a speed of 200kbits.

this is my configuration of vpn server:

port 1194
proto udp
dev tun
sndbuf 0
rcvbuf 0
ca ca.crt
cert server.crt
key server.key
dh dh.pem
topology subnet
server 10.9.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
;push "redirect-gateway def1 bypass-dhcp"
push "route 10.0.1.0 255.255.255.0"
push "dhcp-option DNS 10.0.1.222"
duplicate-cn
keepalive 10 120
comp-lzo
persist-key
persist-tun
status openvpn-status.log
verb 3
crl-verify /etc/openvpn/easy-rsa/pki/crl.pem

That is your ISP upload speed at your server node.

Hi, thanks for your reply, i have got both 300mbit/s on server isp and client isp

Upload speed not download speed :roll:

Same, one provider it's digitalocean (where the server hosted), and on other part is fiberoptic 300mbit synchronous connection

Also, i have got following pings:

39ms pinging the vpn server from WAN

169ms pinging the vpn server from tun0 device (inside vpn)

I'm still trying to understand the problem

This is same speed, over LAN, both two machines are the same:

How is this possible?
