Let's start with a conclusion: when accessing VPS from China to these three locations, the speed rankings are pretty much unsurprising—Los Angeles VPS is number one, San Jose VPS is right behind in second place, and Silicon Valley VPS can be considered in the same tier as San Jose, with not much difference. But if you think that's the whole answer, you might be missing a more important truth: this difference between cities is negligible compared to the differences caused by line type.
Let's first look at the geographical locations of these three cities. Looking at a map of the US West Coast, Los Angeles is at the southernmost point, and San Jose is about 500-600 kilometers to the north. Silicon Valley is essentially a large area around San Jose, so when discussing VPS, Silicon Valley and San Jose are practically synonymous. Further north is Seattle, which is a separate node and not within the scope of today's discussion.
Let's start with Los Angeles. Multiple trans-Pacific submarine fiber optic cables, including the China-US Cable Network (CUCN) and the Trans-Pacific Express (TPE), all have their landing stations in Los Angeles. This means that data originating from coastal cities in China and transported via undersea fiber optic cables will most likely first reach Los Angeles in the United States. This "first stop" status naturally grants it a latency advantage—avoiding transit through other cities reduces hops and saves time.
What about San Jose and Silicon Valley? While geographically farther than Los Angeles, their location further north makes this distance negligible compared to the more than 10,000 kilometers across the Pacific Ocean. The real factor influencing their ranking isn't the few hundred kilometers of road distance, but rather the distribution of fiber optic cable landing points. Because many fiber optic cables terminate in Los Angeles, data arriving in Los Angeles and then needing to be relayed to San Jose must pass through the backbone network within California, adding several hops and milliseconds of overhead.
Real-world testing data confirms this assessment. According to the latest tests in 2026, using the same CN2 GIA line, the average latency for accessing Los Angeles from Shanghai is approximately 148 milliseconds, while in San Jose it's approximately 155 milliseconds. Data from Beijing and Guangzhou generally follows this pattern, with Los Angeles typically 7 to 15 milliseconds faster than San Jose. Other tests show that telecom users accessing optimized lines in Los Angeles can achieve 140 to 180 milliseconds, while San Jose requires 150 to 200 milliseconds. These figures together clearly indicate the ranking: Los Angeles firmly holds first place.
However, I want to mention something that might challenge your perception: this 7 to 15 millisecond difference is almost imperceptible in real-world use. The network latency difference that humans can perceive is usually in the tens of milliseconds or more. What does 7 milliseconds mean? A blink of an eye takes about 100 to 150 milliseconds. So, if you're debating "which is faster, Los Angeles or San Jose?", the answer is "Los Angeles is slightly faster, but this difference isn't worth worrying about."
What you really should worry about is another issue: line type. This point cannot be overemphasized.
Let's look at the dismal state of ordinary lines. In Los Angeles, if you choose a standard international line without CN2 optimization, the latency when accessing from China will spike to 285-298 milliseconds. What does that mean? It's almost 150 milliseconds slower than the 148 milliseconds of a CN2 GIA line! In other words, even if you choose a standard line to save money, and the data center is in a prime location in Los Angeles, the user experience will be significantly worse than a CN2 GIA line in San Jose or even Seattle. The difference caused by the line is ten to twenty times greater than the difference between cities. City rankings are practically insignificant compared to the variable of "line speed."
Therefore, when we discuss "speed rankings," we are essentially discussing "which city has more good lines." Los Angeles ranks first not only because of its southern location and numerous fiber optic landing points, but also because it is the city with the most intense competition among carriers and the highest concentration of high-quality lines on the entire West Coast of the United States. CN2 GIA, CN2 GT, AS9929 (China Unicom's premium network), BGP multi-line optimization—you can find almost any high-quality line you can think of in Los Angeles. With many service providers and intense competition, the cost-effectiveness naturally increases. With comparable configurations, Los Angeles data centers are often cheaper than San Jose.
While San Jose also offers CN2 GIA and BGP optimized lines, the overall number of service providers and the availability of lines are indeed fewer than in Los Angeles. However, San Jose has an advantage that Los Angeles lacks—its proximity to Silicon Valley tech companies. If your business requires deep integration with the US internet ecosystem, such as frequent calls to Google, Amazon, and Facebook APIs, or if your user base includes a large number of North American visitors, then San Jose's network environment may be more suitable. Silicon Valley's network infrastructure is of extremely high quality, with abundant interconnectivity resources and excellent stability.
Here's a simple quick reference table to help you quickly find the right fit:
If your primary priority is access speed for Chinese users: Choose Los Angeles + CN2 GIA without hesitation. This is currently the most mature and reliable combination on the market. Real-world testing shows latency of 135 to 155 milliseconds, with peak packet loss rates below 1%, making 4K video playback effortless.
If your users are distributed across both China and North America: Los Angeles remains a safe choice. It can serve Chinese users well via CN2 lines while also catering to North American visitors thanks to its West Coast location.
If you have extremely high requirements for network stability but are not so sensitive to absolute latency: consider the BGP optimized line in San Jose. Silicon Valley's data center standards are extremely high, with world-class hardware and network interconnection quality, making it particularly suitable for financial businesses, API platforms, or development and testing environments.
If you're only considering a regular line to save money: I suggest you think twice. Regular lines can experience packet loss rates of 5% to 8% during peak evening hours, meaning your users may frequently encounter pages that won't load or images that fail to load. For cross-border e-commerce or any business reliant on conversions, the savings in server costs may not be enough to compensate for lost orders.
Finally, here's an operational suggestion, a step experienced in the industry always takes: before placing an order and making payment, always request a test IP from the service provider. This isn't about distrust, but rather the complexity of the network world; different ISPs, regions, and times of day can all exhibit different performance characteristics. After obtaining the test IP, use traceroute or MTR tools during peak evening hours (e.g., 8 PM to 10 PM) to check the routing path. If a large number of nodes starting with "59.43" appear in the routing table, it's a legitimate CN2 GIA line; if it's full of nodes starting with "202.97," it's a regular 163 backbone network, and caution is advised. Alternatively, you can directly ping the network to check the average latency and packet loss rate by sending 100 packets consecutively.
In summary: Los Angeles ranks first in access speed from China, followed by San Jose and Silicon Valley. However, the significance of this ranking isn't about the difference of a few milliseconds, but rather that the Los Angeles market offers a wider selection of high-quality lines and better cost-effectiveness. Ultimately, city selection is only a "tactical" optimization; the real "strategic" factor determining the experience is always whether you choose a CN2 GIA or a regular line. Remember this: it's better to buy a CN2 GIA line in Los Angeles than a regular line in San Jose. The former is so fast you'll forget the server is in the US, while the latter is so slow you'll wonder if you're still using dial-up.
