Why Bitbucket used explicit core.packedgitlimit = 256m?

[Alexey_Efimov]

Why follow values are default for repositories on Server with 64bit arch and 128GB of RAM?

[core]
	repositoryformatversion = 0
	filemode = true
	bare = true
	packedgitlimit = 256m
	packedgitwindowsize = 32m
[http]
	receivepack = true
[gc "stash-refs/pull-requests/*"]
	reflogExpire = never
	reflogExpireUnreachable = never

For packedGitLimit its default value on 32-bit system and 8Gb is default on 64-bit systems. Soo it look like misconfiguration...

I don't know the answer here so I'm just commenting, but https://answers.atlassian.com/questions/239205 might be helpful. To paraphrase, this is just our standard configuration (it's hardcoded for every repo, afaict) because it seems to avoid issues across our supported platforms (apparently the 64-bit default caused issues on OSX in some cases).
