Several factors can result in poor TeraCLOUD performance.

* See also: What is the maximum speed?

Possible Causes

TeraCLOUD operates over the internet, therefore various networks must be traversed with in order to reach your local environment. For this reason, pinpointing the exact cause of poor performance can be difficult. The following information below may assist users experiencing issues.

  1. 1. Check load time speed for other sites.
    • If websites other than TeraCLOUD are also slow to load or respond, there may be an issue with your internet connection.
    • Are load time speeds slower than usual for sites other than TeraCLOUD? 
    • Are connectivity issues occurring?
  2. If only connections to TeraCLOUD are slow.
    • The following issues could be caused by:
      • Congestion on TeraCLOUD systems end. If congestion continues for an extended duration, all users can find greater details posted on TeraCLOUD's website.
      • Excessive load on your device. Please check your device's resource usage for signs of a problem.
      • A routing issue between the user's Internet Service Provider (ISP) and TeraCLOUD. In this event, immediate action is required involving your provider and TeraCLOUD. This issue can not be resolved by the user.

In the second situation, it is technically possible to improve speeds by establishing a direct connection between your ISP and TeraCLOUD. However, as mentioned above, such issues regarding the user's ISP issues can not be resolved by the user or TeraCLOUD, and must have full cooperation of the user's ISP.

Trace your route to TeraCLOUD

TeraCLOUD can better understand poor connection issues with the assistance and input of the following information. In general, TeraCLOUD usage patterns frequently involve transmissions from the end of the user to TeraCLOUD. Therefore, information from the user's end is required for an accurate representation. 

The Traceroute command (Tracert in Windows) displays the network route to a remote host, allowing a real-time investigation of intermediate routers along the pathway. While this is not directly related to bandwidth (upload and download speeds), the response times shown for each router can be used in a simple evaluation of network capabilities.

 

How to use Traceroute

On Windows systems:

In this example, we run Tracert to yura.teracloud.jp. Adding the -d option performs the trace without DNS resolution.

C:\>tracert -d yura.teracloud.jp
Tracing route to yura.teracloud.jp [103.49.141.114]
over a maximum of 30 hops:

  9    13 ms    12 ms    12 ms  103.49.141.114

Trace complete.

On Unix-like systems:

Here we run Traceroute to yura.teracloud.jp. The -I option specifies that Internet Control Message Protocol (ICMP) will be used, and -n conducts the trace without Domain Name System (DNS) resolution.

$ traceroute -I -n yura.teracloud.jp
 1  **.**.255.254  5.924 ms  5.743 ms  5.838 ms
 2  **.**.158.190  7.037 ms  6.303 ms  6.442 ms
 3  **.**.77.125  5.839 ms  5.843 ms  11.042 ms
 4  **.**.77.225  5.763 ms  5.844 ms  5.846 ms
 5  **.**.109.25  9.302 ms  8.768 ms  8.577 ms
 6  **.**.224.72  9.345 ms  8.704 ms  8.705 ms
 7  **.**.140.193  9.311 ms  9.378 ms  9.302 ms
 8  **.**.140.18  12.211 ms  12.236 ms  12.826 ms
 9  103.49.141.114  12.692 ms  12.836 ms  12.279 ms

The values shown in milliseconds (ms) are each router's response time, representing the time taken to travel to the given router and back.

If response time increases greatly at a particular point, it is likely that an issue with the internet route is causing performance problems.
