It seems the problem is with NSURLDownload (which is used by Sparkle to download the zip with the new version) and S3 (which is where the GitHub releases files are actually hosted). The same file downloaded with Sparkle from mac.hivewallet.com or with curl/wget from S3 is downloaded in about half a minute or less. If I don't find a solution for this, it might make sense to host the files somewhere else...
