We were at first vexed and then later delighted when a bug loading data in iD led us to discover some big performance improvements for OpenHistoricalMap.org.
We thought we might need to just throw more resources at the server, but a timely comment from OSM contributor MMD helped steer us in the right direction.
Ruben from Development Seed got the MUCH faster CGI-map configured, and now let’s hear from Minh directly how much faster everything is:
CGImap has dramatically improved my experience as a contributor to OpenHistoricalMap. Before, I could barely upload boundary relations without JOSM timing out and retrying, and using iD sometimes felt like reverting to a dialup connection. Now I can upload and download without going out for a walk while I wait.
