Concurrent Requests¶

Requests are made using httpx2's asyncio support. This means that within the eve-link ratelimiting scheme, requests are made all at once. This can make a huge difference even with single EsiRequests, because many of the endpoints are paged. Internally, those pages are turned into requests themselves, and fetched at the same time. The combined pages are then all returned as one response. For example, the region of space with Jita might have 400 or more pages of market order data. At about .5 seconds per page, that would take over 3 minutes if done one after the other. But making concurrent requests cuts that time down dramatically. The ESI api does not rate limit by successful request (Though that is changing) but still, please don't DDOS the servers. Keep resonable rate limit settings.
