Logistics of a CQ or AEM Package Upload

Uploading a package to AEM via Package Manager will cause it to be first incrementally saved in the folder designated as java.io.tmpdir in the form of a file named something like this: __crx8317477248625593413.dat Once installed, it will be automatically deleted.

To speed up package upload as well as DAM asset uploads, point java.io.tmpdir at a locally direct-attached drive that speaks SATA or SCSI, not a network drive. For the Amazon Cloud, this would be the “ephemeral” drive, also called the “instance store”.
