Hello,
I’m trying to find information about load testing TSW200 and TSW101. I want to know, how much throughput does it take, to cause the switch to lose packets? How does it behave under constant load?
I have called customer support, however they weren’t able to provide an answer and asked me to post it on forums.
Hello @test,
Our deepest apologies for the delayed response.
Regarding the overall switching capacity, the TSW101 features a 10 Gbps non-blocking switching bandwidth, while the TSW200 features 20 Gbps non-blocking switching bandwidth.
It is physically impossible for a single connection to reach these backplane limits due to the bottleneck of the individual Ethernet ports, which operate at a maximum speed of 1 Gbps. Even under full load—with an equal number of servers and clients transmitting simultaneously at maximum Gigabit speeds—the combined throughput across all active ports would reach approximately 5 Gbps for the TSW101 and 10–11 Gbps for the TSW200.
As for the devices’ long-term performance and stability under continuous full load, we have forwarded your question to our testing department for further investigation. We will update you as soon as we receive their feedback.
We appreciate your patience and will forward any additional information as soon as it becomes available.
Best regards,
P.
Hello @test
We’re writing back regarding your questions with information provided by our testing team.
Under properly distributed testing conditions, with symmetrical many-to-many port mapping (Mesh), both switches are able to achieve 100% throughput with 0% packet loss.
Packet loss may occur in cases of port congestion. For example, if three servers are each transmitting at 1 Gbps to a single client connected through one 1 Gbps port, the receiving port is limited to 1 Gbps. As a result, packets may be dropped due to congestion.
Our testing team also confirmed that when sending large bursts of packets using various packet sizes (64, 128, 256, 512, 1024, 1280, and 1518 bytes), both devices experienced 0% packet loss across different test durations.
Below, you can find the graphs from the testing results:

Additionally here are a few screenshots with some test results from both devices:

Hope this answer your questions, if you have any other questions please let us know.
Best regards,
P.
