Let’s briefly evaluate the situation of profitserver’s unlimited traffic VPS in Los Angeles, USA.

profitserver, a service provider founded in Chelyabinsk, Russia in 2003, what we pay the most attention to is probably their VPS business. The default is to not limit traffic and support PayPal, credit cards, cryptocurrency and other forms. Payment. We plan to first evaluate the VPS in its computer room in Los Angeles, USA. The data is for reference only. Please pay attention to other computer rooms in the future!

After getting the vps, I opened bbr and found that the CPU frequency was 2.2GHz and I blindly guessed it was e5-2660v2 (don’t take it seriously, it’s just random). The hard disk I/O was about 396MB/S:

FIO tests hard disk read and write in more detail, as follows:

speedtest.net's three network nodes in mainland China test the uplink and downlink effects of VPS in mainland China:

To compare the effect of the evening rush hour, pay attention to the comparison with the above picture:

Testing of other nodes in Asia:

Iperf3 test results in Europe and the United States:

The webmaster of the files stored on the VPS is Guangzhou Telecom, and the download speed is approximately 6.7MB/S:

The evening peak test speed is 8.9MB/S, which shows that the server network load may be higher during the daytime test:

Pay attention to the delay, ping.chinaz.com provides data on more than 60 nodes in mainland China:

For the outbound telecommunications journey, take cogentco:

China Unicom’s outbound journey takes GTT:

For the outbound journey, take CMI to cogentco:

Judging from the outgoing journey of the three networks, the server seemed to be hosted in Performive's Los Angeles computer room.

Return to China Telecom:

Towards Beijing, take the cogentco from San Jose to connect to the telecommunications backbone;

Shanghai direction, directly connected from the Los Angeles telecommunications node;

Guangzhou direction, directly connected back from San Jose telecom node;

Return to China Unicom: Take GTT to connect with China Unicom AS4837 to return home

Return, move to mainland China:

Beijing direction, directly connected back from the Los Angeles mobile node;

In the direction of Shanghai, come out from San Jose cogentco to connect with the mobile backbone;

In the direction of Guangzhou, come out from Los Angeles cogentco to connect with the mobile backbone;

Unix bench:

A rough summary:

Whether it is the outbound or return trip, at least there is no detour to other places, but it is all via cogentco or GTT, and part of the return trip is directly connected to the operator's nodes in the United States; generally speaking, the network advantage is not great, but it is not a popular computer room. There is no traffic limit again, and judging from the test, the bandwidth should be 1Gbps. So, try it if it suits you.
