You might be interested by the following config variables:

	core.packedGitWindowSize
	core.packedGitLimit
	core.deltaBaseCacheLimit
	pack.windowMemory
	pack.deltaCacheSize

Certainly one or more of them could be tweaked in the remote repo to solve your problem. But since your problem happens on push then you should look at the core variables first.
