Hardware and Performance / OPNsense and CPUs with P- and E-cores
« on: November 08, 2023, 03:20:45 pm »
Anyone here have experience on the given subject?
I've been looking for a 10G capable router and came up with a few options. My go-to pick (https://www.aliexpress.com/item/1005006152906369.html?algo_exp_id=d8421ce0-c78e-4c54-8d6f-2d89233de121-3&pdp_npi=4%40dis%21EUR%21799.00%21559.3%21%21%21799.00%21%21%402101c59116994502417361713e1abd%2112000036003683813%21sea%21FI%211621031731%21&curPageLogUid=sA62A9GurPWX, sorry for that abysmal link) for now is based on a Intel i5 1240P which has a 4P+8E-core layout. Has anyone here tested such CPUs with OPNsense? I'm mostly interested in the stability of the performance since there is quite a big performance gap between P and E cores.
This problem will probably be fixed in the future once FreeBSD updates the scheduler. There is also current "fix" to run OPNsense virtualized and point the specific higher performance cores to the VM. Third option would be to disable the E-cores, but this implementation seems a bit broken in the BIOS and results in limited performance with P-cores.
