CONFIG_IP_VS_NQ: never queue scheduling

General informations

The Linux kernel configuration item CONFIG_IP_VS_NQ has multiple definitions:

never queue scheduling found in net/netfilter/ipvs/Kconfig

The configuration item CONFIG_IP_VS_NQ:

• prompt: never queue scheduling
• type: tristate
• depends on: (none)
• defined in net/netfilter/ipvs/Kconfig
• found in Linux kernels: 2.6.28–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD
• modules built: ip_vs_nq, ip_vs_nq

Help text

The never queue scheduling algorithm adopts a two-speed model. When there is an idle server available, the job will be sent to the idle server, instead of waiting for a fast one. When there is no idle server available, the job will be sent to the server that minimize its expected delay (The Shortest Expected Delay scheduling algorithm).

If you want to compile it in kernel, say Y. To compile it as a module, choose M here. If unsure, say N.
