Singapore Netflix VPS Speed And Latency Compared To Nodes In Other Regions

1.

Introduction and Test Objectives

Objective: To compare the network performance of Singapore (SG) VPS with nodes in other regions (such as the US, Europe, Japan, Hong Kong) when playing Netflix. Breakdowns: Explain why you need to test—latency determines the first screen time, bandwidth determines maximum clarity, packet loss affects stability. Clearly define test outputs: RTT (ms), packet loss rate (%), bandwidth (Mbps), and startup buffer time (s).

2.

Preparation: Purchase/prepare VPS and testing equipment

Select nodes: At least prepare a Singapore node with another or more comparison nodes (for example: Los Angeles, Tokyo, Hong Kong, Frankfurt, USA). Sub-segment: Recommended specs—1 core/1GB memory is sufficient for network testing, but for actual testing, 2 cores/2GB or more is recommended; System recommendation: Ubuntu 20.04. Records each VPS's public IPv4, region, bandwidth limit, and provider information.

Install the required tools on the VPS (Ubuntu example).

Step command: After SSH login to the VPS, run the following command to install the tool. Subsegments: Common commands (entire segments are copied and pasted at once):
sudo apt update && sudo apt install -y iperf3 mtr traceroute dnsutils wget curl tcpdump net-tools
Install speedtest (Ookla CLI):
sudo apt install -y gnupg1 apt-transport-https dirmngr
curl -sS https://install.speedtest.net/app/cli/install.deb.sh | sudo bash
sudo apt install -y speedtest
Note: If you are using CentOS or other distributions, please use the corresponding package manager.

Basic network testing process from client (local) to each VPS

Step 1: ping test (latency and stability):
Execute on the local terminal: ping -c 20 VPS_IP, record the average RTT (average, minimum, maximum, packet loss). Sub-segments: It is recommended to test at multiple locations (home broadband, mobile 4G/5G) to obtain representative data. Step 2: traceroute (path and hop):
traceroute VPS_IP or mtr -rw VPS_IP to check if there are poor links or long jumps.

5.

Bandwidth testing: iperf3 and speedtest

Starting the iperf3 server on the VPS:
iperf3 -s --logfile iperf_server.log
Run locally as a client (testing upstream/downlink to VPS):
iperf3 -c VPS_IP -P 4 -t 30
Note: -P 4 stands for Concurrent Stream, simulating a multithreaded scenario. Recorded throughput (Mbps). Segments: Use speedtest to test the nearest speedtest node as a reference: speedtest -s SERVER_ID.

A method specifically for testing the Netflix viewing experience

Browser testing steps (Chrome recommended): Subsections: 1) Clear the cache and log in to Netflix; 2) Open Developer Tools (F12) - > Network and play clips of the same episode/bitrate; 3) Records the first buffer time (from click to screen display), playback resolution, and total buffer count. Tool testing: Use youtube-dl or ffprobe to check the download speed of DASH/HLS slices; If using the official Netflix client, pay attention to playback bandwidth and CDN nodes (which can be determined from the requested domain name).

7.

Server-side measurement: packet capture and latency distribution

Using tcpdump on VPS to scrape Netflix-related traffic (for analysis only, do not store sensitive data): Subsegment: sudo tcpdump -i eth0 host CLIENT_IP and port 443 -w netflix_client.pcap, then use Wireshark or tshark to analyze TLS handshakes and throughput for each TCP stream. Continuously monitor client latency fluctuations using MTR: MTR -rwc 100 CLIENT_IP.

8.

Compare data recording templates with how to interpret results

Template suggestion: Create a CSV/Excel column: node, average RTT (ms), jitter (ms), packet loss (%), iperf throughput (Mbps), first buffer (s), maximum resolution, number of buffers. Subsegments: Key Points — If SG RTT is significantly lower than other regions and throughput is high, the viewing experience is usually better; If RTT is low but packet loss is high, it indicates unstable links and the cause of packet loss should be monitored.

9.

Common influencing factors and optimization recommendations

Factors include: direct connection/interconnection between the carrier and the CDN, the VPS provider's outbound bandwidth and BGP strategy, the physical distance from the data center to the Netflix CDN, and the quality of the intermediate link. Sub-segment: Optimization suggestions—select data centers with good international bandwidth and enable BBR congestion control (sysctl net.core.default_qdisc=fq; net.ipv4.tcp_congestion_control=bbr), adjust MTU/MSS, use multi-line loads, or smart routing (BGP Anycast or commercial CDN).

10.

Example: Comparison between Singapore node and Tokyo node (practical example).

Steps: Perform 5 pings, 3 iperf3 tests, and 2 browser playback tests during the same time period, and record the results. Segments: If Singapore's RTT averages 25ms and throughput is 200Mbps, while Tokyo's RTT is 40ms and 180Mbps, Singapore has advantages in latency and throughput. However, if Singapore loses 2% and Tokyo loses 0.1%, Tokyo's playback stability may be better.

11.

Q: Why is the Singapore node sometimes faster than neighboring regions (Hong Kong/Japan)?

Answer: Network connectivity and backbone pathways are key. Singapore is an important internet hub in Southeast Asia, with many international direct connections and large CDNs having nodes or excellent peering in Singapore. Additionally, good peering between VPS providers and local ISPs can significantly reduce RTT and packet loss.

12.

Q: How can I tell if it's a VPS node issue or a local ISP issue?

Answer: By comparing tests from multiple client locations to the same VPS (remote ping/iperf), as well as testing from the same client to multiple VPSs. If only local nodes have high latency or packet loss, the problem lies with the local ISP; If only a VPS has poor metrics, the problem lies with the VPS or its upstream link.

13.

Q: Practical deployment advice: Should I choose Singapore or other nodes to view Netflix?

A: If your audience or you yourself are mainly based in Southeast Asia or Australia, Singapore is usually the preferred choice (low latency, good peering). If the target is North America/Europe, nodes close to those regions should be chosen. Ultimately, actual measured RTT, packet loss, and playback experience are used as the standard, with multi-node load and intelligent routing applied if necessary.
