Realtime to the Million!
Statistics
This benchmark was performed with a single WebSocket Server and 16 machines connecting to this server.
Simultaneous Users
Number of simultaneous users connected over time.
| Metric | Description |
|---|---|
| Users | Number of simultaneous users. |
| Connected | Number of users with an opened connection. |
Response Times
Response time at a given point of time.
As seen, the response time was very constant until the limit of one million connections was reached.
| Metric | Description |
|---|---|
| Connect | Duration in milliseconds of the handshake. |
| Request | Response time in milliseconds for establishing the connection. |
Traffic
Network traffic or data traffic moving across the network at a given point of time.
| Metric | Description |
|---|---|
| Sent | Size of requests in bytes. |
| Received | Size of responses in bytes. |
Errors
Errors that occured when trying to connect or during an already established connection.
As seen, there were no errors until the limit of one million connections was reached.
| Metric | Description |
|---|---|
| Connect | Number of connections that failing to connect. |
| Disconnect | Number of connections that disconnected. |

Average Response TimePerformance
This benchmark was performed on a DigitalOcean General Purpose Droplet with 32 cores and 128 GB of memory.
Usage
The respective value of what percentage is actually being utilized. The CPU usage is an indicator of how much stress the processor is currently undergoing, and, what capacity is still available.
The drop at 500 seconds results from no more new connections are established. That means, the last value reflects the load to maintain all connections.
| Metric | Description |
|---|---|
| Usage | CPU Usage in %. |
Load
The load represents the average system load over a period of time. 1.0 on a single core cpu represents 100% utilization.
Note that this benchmark is using a machine with 32 cores.
| Metric | Description |
|---|---|
| Load | CPU Load by cores. |
Memory
Amount of system memory used over time in MB.
| Metric | Description |
|---|---|
| Used | Used memory in MB. |
