We've been packaging pandas in a lambda which is used to perform some calculations, but being a 50 MB zip file makes cold starts of about 6-8 secs. We're lucky that the service has little use, thus our way to workaround it is by having a lambda warmer which is run every 5 minutes and invokes N pandas lambdas. I'd be very interested in knowing if Layers has some feature to avoid this kind of issue.
