nodejs + postgresql way too slow

I’m not sure whether this is an issue with pg or not, but I am not being able to get a reasonably enough fast app using node-postgres (pg). I wrote a question on stackoverflow but it seems nobody was able to help me.

Here is the post on stack overflow. I thought it would be better just to link it instead of duplicating everything here. (Just tell me in case it would be better to have the full problem described here)

Thanks in advance for any help.

First thing I can see is you’re still running the query twice on every request. Remove all that stuff about the QueryStream and just call res.send(result.rows) directly. There’s no reason to go through the hoops of streaming results to the client if there are only 1,000 rows. Possibly after 10k rows you’ll start seeing an advantage to streaming, but for the most part it only becomes apparent when you’re moving massive amounts of data. In your example you’re still selecting the entire 1,000 row result set into memory, disregarding it, and then doing the query a 2nd time and streaming the results to the client.

All right. I’ll keep your recommendation in mind in my next attempts to understand what is going on. Thanks a lot for your help and time. I really appreciate it.
