Sure. What is the speed of the internet service you are using? Speeds less than 5 Mbps download and 1 Mbps upload would be perceived by most as slow to begin with. The VPN runs on this internet service with overhead so if this was your internet service your result would be even lower than this if you tried www.speedtest.net. Sometimes a faster internet service is essential.
An additional issue to consider is what is the score VPNGate assigns to the site you are trying to connect to? Pick sites with higher scores from the column to the right hand side of the table. Sites with low scores typically have slower line speeds.
Lastly use Softether VPN client for your connections rather than L2TP, SSTP or OpenVPN clients. This will help with more speed.
