Adding a local SSD cache on the VPS containing all except the last 1-3 zoom levels for each map reduces latency for 66% of requests. The majority of image requests come from the first few zoom levels, representing less than 25% of a given map's images. With hosting working, it's time to start making the site faster. That means 75% of a map's images are in the max rendered zoom level.Ī diagram of how each zoom level is 4x larger than the previous As a map is zoomed in, it requires 4x as many images to show the same area.
Leaflet maps work by loading images at the user's X/Y/Z coordinates to render the current view. Unfortunately, the latency from the user -> VPS -> B2 was sub-par averaging 800-1200ms in the US. To remove it, I added a VPS proxy to rewrite paths and add a few 301 redirects. Backblaze B2 is a better fit because upload API calls are free, egress bandwidth is $0.00/GB to Cloudflare, and storage is 1/4th the price of the competition.īackblaze B2 requires a prefix of /file/bucketName on all public files, which I don’t want.
For this use-case, $0.05 per 10,000 upload API calls and $0.08 to 0.12/GB for egress would add up quickly. However, after 3.5 months in operation, contains 17 million map images (>1TB). Amazon S3 and Google Cloud Storage are the obvious choices for low-latency object storage. Leaflet maps contain thousands of small images for X/Y/Z coordinates. A Leaflet map provides a Google Maps-like experience allowing viewers to pan and zoom throughout the map almost as if they are playing the game. Due to the size and detail of the game, it can be difficult to share an entire factory through a few screenshots.
Once production starts getting up to speed, alien bugs start to attack the factory requiring strong defenses.Ī Factorio factory producing many different items.Ī Factorio military outpost fighting the alien bugs.Ī Factorio map view of a small factory, that’s still too big to easily share fully with screenshots.Īt, I am building a place for the community of Factorio players to share their factories as interactive Leaflet maps. Resources move along the production line through multiple means of transportation such as belts and trains.
Players mine resources, research new technology and automate production. He is building a community site for the game Factorio centered around sharing user creations.įactorio is a game about building and maintaining factories. The following is a guest post by Jacob Hands, Creator of.
