Hi!
Is there any possibilities to define global maxconn parameter value for one haproxy process and known CPU/Memory/Network parameters? I mean without load testes.
All I’ve found in documentation is 3.5. Sizing
thank you in advance
That is a little like trying to nail jelly to the wall (A developer I know once said that!).
I like how pfsense show rough memory needed for connections in their WebUI:
| Connections | Memory usage | |
|---|---|---|
| 1 | 50 kB | |
| 1.000 | 48 MB | |
| 10.000 | 488 MB | |
| 100.000 | 4,8 GB | |
| Calculated for plain HTTP connections, | ||
| using ssl offloading will increase this. |
However, that is also a BSD distribution so not the same as Linux, I remember something about 33kB per conn… I think it was around 17 for the kernel and 16 for the userspace but that was such old data even if correct then it’s not likely now.
