12/30/2021, 4:41 PMHey guys, with SST lambda cold start (in debug mode) takes too much time... Is there a plugin like serverless-optimize available for SST?

minifytrues

12/30/2021, 9:52 PMminify is defaulted to true. I am just building the notes demo app and running it in local mode. The first time i launch it takes > 15 sec. Any suggestions? @thdxr, @Derek Kershner?

12/30/2021, 9:53 PMDax is likely to ask how big your lambda is.

thdxr
12/30/2021, 9:55 PM^ yes haha but if it's just the notes app it should be normal. Hmm can you send me you .build/debug log

12/30/2021, 9:59 PM@Samir Baid, are you on the newest version? I had a similar symptom a few versions ago.

12/31/2021, 2:32 AM@Derek Kershner i am using cli version 0.54.4
Samir Baid
12/31/2021, 2:58 AMi dont know what happened, but i deleted the entire stack (had to delete dynamoDB and S3 manually) and redeployed. Now things look much better
Samir Baid
12/31/2021, 3:28 AM@Derek Kershner, @thdxr it is happening again. Apparently when the stack is deployed from scratch things are faster, but if we add new lambdas to existing stack cold start becomes bad... This time took 17.58 sec

Samir Baid
12/31/2021, 4:10 AMswitching to 0.55.1 seems to have done the trick... Now things are fast again... i'll do some more tests and if i see concerns will let u guys know... Thanks a lot for helping out

@Samir Baid Ah nice. This sounds like an issue we fixed in 0.55.0!
