Re: [Kea-users] Kea VM sizing ?
Our Kea solution is pretty lightweight: 2 VMs running Ubuntu 18 2 vCPUs per VM 8 GB vMEM (but using less than 4 GB) DHCP VMs use hosted MySQL so neither VM runs a database process locally. We're serving about 11K clients, load average hovers pretty close to zero the whole time. hth, Klaus On Tue, Apr 12, 2022 at 7:24 AM David Ramsey wrote: > Thank you for the feedback, folks, both on-list and off. > > Bjørn - your scenario very closely resembles what we plan to deploy - > thank you for the detail.

Thank you for the feedback, folks, both on-list and off. Bjørn - your scenario very closely resembles what we plan to deploy - thank you for the detail. I am impressed that you can serve 40k+ subs with only 2 vCPU and especially only 2GB RAM -- great news. --dmr On Tue, Apr 12, 2022 at 5:08 AM Bjørn Skovlund wrote: > Hi David, > > We're running well over 40K customers on a set of HA KEA DHCP on 2 vCPU > and 2 GB memory, with MariaDB backend (placed on the VMs).

Re: [Kea-users] Kea VM sizing ?
Hi David, We're running well over 40K customers on a set of HA KEA DHCP on 2 vCPU and 2 GB memory, with MariaDB backend (placed on the VMs). Lease time is 1 hour and we can recover from outages. We're running Flex ID and forensic logs. CPU usage is averaging about 25%.

Re: [Kea-users] Kea VM sizing ?
Hey, we don't have such document yet, but I can point you to our recent performance tests report, which on first page described hardware used and in most charts it adds memory and cpu usage. It also describe multi threading settings (it may differ between systems) But I will give you small "it depends", mostly it depends on 3 factors, traffic characteristics you expect (how often clients ask for lease), lease backend you use and roughly how many clients are in your network * db backends (mysql and pgsql) needs more cpu cores but less memory and are generally slower than memfile * memfile needs more memory especially if you are handling huge number of clients, and over all CPU usage on system is smaller (you run just Kea not additional database) report: https://reports.kea.isc.org/performance/stable/2.0.2/report.html Thanks for using Kea, Wlodek Wencel QA Engineer, ISC On 08/04/2022 23:07, David Ramsey wrote: Is there any virtual machine sizing data available for ISC Kea DHCP ?

[Kea-users] Kea VM sizing ?
Is there any virtual machine sizing data available for ISC Kea DHCP ? In particular I don't know how to spec out RAM and # vCPUs.. I realize "it depends", of course, but are there any ballpark guides or formulas anywhere? Thanks, --David -- ISC funds the development of this software with paid support subscriptions.
