The Crystal Programming Language Forum

Why are & so slow?

I recently learned about Crystal Language and really find it exciting. Trying out a few examples of my own, I came across and as useful sites to lookup existing shards. However, thinking that these sites cater to Crystal language users and would be built using Crystal themselves, I’m perplexed as to why they are sooo slow? Example request below took close to 7s. Can someone please explain why this is so?

Thank you in advance!

Pretty sure they’re just wrappers around Github’s search API. Try which runs its own database.

It loads fast for me. It might be that these are hosted on heroku, so they are taken down from time to time.


Thank you @jhass, that makes more sense. Amazing language, already loving it! Wrote a shell based executable to streamline local lookups of US zipcodes and SQLite backend…HYPERFAST!!!
