Fix High Latency/Ping

Measuring Latency

# Round-trip time (RTT)
ping -c 10 YOUR_SERVER_IP

# More detailed
mtr --report YOUR_SERVER_IP

Normal latency:

Same continent: 5-30ms
Cross-continent: 100-200ms
Global: 200-400ms

Find Latency Bottleneck

Using mtr (My TraceRoute):

mtr YOUR_SERVER_IP

Look for hop with high loss or high latency jump.

Fix 1: Choose Nearest Data Center

When creating VPS, select location closest to your users.

Hostxpeed offers multiple locations. Migrate if needed.

Fix 2: Use CDN for Content

Cloudflare, BunnyCDN, etc. cache static content globally.

Fix 3: Enable TCP BBR (Congestion Control)

# Enable BBR
sudo modprobe tcp_bbr
echo "tcp_bbr" | sudo tee -a /etc/modules-load.d/modules.conf

# Set congestion control
echo "net.core.default_qdisc=fq" | sudo tee -a /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

# Verify
sysctl net.ipv4.tcp_congestion_control

Fix 4: Optimize TCP Settings

# Increase buffer sizes
echo "net.core.rmem_max = 134217728" >> /etc/sysctl.conf
echo "net.core.wmem_max = 134217728" >> /etc/sysctl.conf
echo "net.ipv4.tcp_rmem = 4096 87380 134217728" >> /etc/sysctl.conf
echo "net.ipv4.tcp_wmem = 4096 65536 134217728" >> /etc/sysctl.conf
sudo sysctl -p

Fix 5: Check for Packet Loss

Packet loss increases effective latency due to retransmissions:

# Test packet loss
ping -c 100 YOUR_SERVER_IP | grep loss

Loss > 1% indicates network problem. Contact Hostxpeed if internal.

Fix 6: Use HTTP/2 or HTTP/3

Enable HTTP/2 in Nginx/Apache for multiplexed connections.
