Troubleshooting Very Average Wireguard Performance on IONOS
I’ve been obsessing over this on and off for about a month, and I just can’t seem to figure it out. The situation is as follows: public internet ———-> VPS <====WG Tunnel====> pfSense ———-> LAN/Server I have a Wireguard tunnel set up to route all traffic between my pfSense LAN and a VPS. This means […]
Weird Network Problems in XCP-NG
I have no idea what is going on. I’m getting consistently inconsistent throughput and latency issues. This is a post to collect my findings so far… Not very interesting to anyone else but me. Ping via PIFs: No problems there. Pings between VMs, using VIFs: Not terrible, but not amazing. Throughput tested with iperf3: Throughput […]
MySQL Benchmarks – NFS vs Local Storage
Recently, I migrated my containers from a standalone Docker node to Docker Swarm. On the standalone node I used a local VHD for persistent storage, but now I’m using NFS Docker volumes defined in the compose file. I knew I’d take a slight performance hit serving the files over NFS, but I was happy to […]
Optimising VM Performance on XCP-NG – domU Clock Source
My 11G Dell R610 is over a decade old – and it’s beginning to show it’s age. The price to performance ratio is pitiful, so it’s vital that I squeeze every last drop of FLOPS from this computational dinosaur.
The ULTIMATE HAProxy Configuration
Need an all in one, do everything, all singing, all dancing reverse proxy? Look no further! I’ve been building an ultra dense HAProxy system which will take care of SSL passthrough, SSL termination, Let’s Encrypt certificate generation, conversion and autorenewal and the other benefits that come with HAProxy, like caching and load balancing.
GPT-J-6B Chatbot Experiments
GPT-J is a 6 billion parameter model and does a shockingly good job at writing stories, answering questions, and generally giving people existential crises regarding their job security.
Deploy a Local Kubernetes Cluster on Debian 11
From someone who has no idea how to deploy a Local Kubernetes Cluster on Debian 11. Kubernetes is an amazingly powerful tool… yada yada yada. Chances are you’re here because you’ve already heard how great it is. So, if you’ve had the same idea as me and want to set up a local k8s cluster […]
Homelab Part 1: ORIGINS
During the first COVID lockdown, I found a new way to occupy myself and my wallet; I was going to learn how the internet works or go broke trying. That was definitely not my original plan, but it’s definitely what ended up happening and led to the rise and fall of my homelab & private […]
Private Cloud (2021)
My Private Cloud/Homelab has been my main hobby since 2019. Growing and shrinking as needed, it’s provided an essential leaning environment for as many open source services as I have time for. I attribute it’s longevity thanks to the fact I can take it anywhere with an internet connection. Through careful planning, I’ve actually downsized […]
Tuning VM Performance on XCP-NG for Dell 11G Servers
There’s a great white paper by Dell on BIOS settings for optimal performance on 11G servers (definitely worth a read if this post is relevant to you), but it doesn’t tell the whole story. The thorough testing in the paper was performed with regard to High Performance Computing applications, which is a good indicator of […]
