Benefits of this port:
- Optimized for faster runtime. (600% faster with 6 threads & when it's not in deskshare mode)
- No Node.js, so no troubles with node versions conflicts and packages
| Type | Node.js | Go (1 Thread) | Performance increase |
|---|---|---|---|
| Long recording no drawings | 885s | 892s | ~ 0% |
| Big canvas not long duration | 43s | 17s | ~ 252% |
| 4h long with a lot of slides | 4455s | 1851s | ~ 240% |
The new go implementation is scalable over the -t tag which is not yet implemented in the node.js version.
With the same recording above "4h long with a lot of slides" we get the new times:
| Thread count | Time | Speed increase (compared to node.js) |
|---|---|---|
| 2 | 1115s | ~ 400% |
| 3 | 905s | ~ 490% |
| 4 | 813s | ~ 540% |
| 5 | 773s | ~ 570% |
| 6 | 734s | ~ 600% |
