Sandbox performence

[tranbathanhtung]

I have a problem with sandbox when reconnecting. Cold start is slow. It's taken around 5-6s to wake up, sometimes up to 10-12s. Any solution to improve cold start time?

Hey @tranbathanhtung ! Assuming this is on production - can you describe your traffic behaviour? Is there a lot of bursty traffic? This shouldn't be the case unless you have a ton (1k+ sandboxes being created in bursty fashion). Furthermore - have you set max_instances in your wrangler config? If so, what's the value? The default is 20 and is recommended until you go live with production customer traffic - in which case you can bump it up till a max limit (and if this doesn't suffice, you can speak with us to manually get higher limits on your account).
