database directly (where the "http://" and "rsync://" protocols
count as direct access).
+core.packedGitWindowSize::
+ Number of bytes of a pack file to map into memory in a
+ single mapping operation. Larger window sizes may allow
+ your system to process a smaller number of large pack files
+ more quickly. Smaller window sizes will negatively affect
+ performance due to increased calls to the opreating system's
+ memory manager, but may improve performance when accessing
+ a large number of large pack files. Default is 32 MiB,
+ which should be reasonable for all users/operating systems.
+ You probably do not need to adjust this value.

core.packedGitLimit::
Maximum number of bytes to map simultaneously into memory
from pack files. If Git needs to access more than this many
