I'm getting ready to spin up a v10 Linux Proxy for my B&R on an ESXi cluster. This will be a virtual machine.
From a post on Reddit three months ago, Gostev mentions this:
For CentOS he goes on to say:...here are some curious backup proxy stress testing results with the current v10 build, with different job and compression settings.
WS2019: Most consistent performance overall regardless of proxy load.
Ubuntu 19, Debian 10: By far top performance specifically under heavy load, worse than WS2019 under lighter loads.
openSUSE 15.1: Very consistent and only slight worse performance than WS2019.
CentOS8: Most inconsistent performance (all over the place depending on proxy load).
CentOS7: Most terrible performance overall, not recommended
"This is likely due to the default tune of CentOS. Experienced users will apply throughput oriented tuned profile to solve the issue. But since almost all users just go with the default OS settings, we need to establish some general recommendations for out of the box configurations."
From the v10 user guide, I am aware of the following requirements and limitations that apply to Linux backup proxies:
• bash shell and SSH are required
• The user account that you specify for the Linux server must be a root user or user elevated to root.
• The disk.EnableUUID parameter of the Linux server must be set to TRUE in the VMware vSphere client.
• Only the Virtual appliance transport mode is available.
So, I am further wondering:
1. What is the recommended distro for best performance?
2. What is the recommended configuration for memory/disk?
3. What is the recommended performance tuning?
anything else?
