When I start Xcode 7 beta it spends a lot of time doing some very hefty CPU work. Diagnostic Reports show this:
75 ??? (com.apple.dt.Xcode.sourcecontrol.Git + 42837) [0x10d8c6755]
74 git_status_list_new + 961 (libgit2.dylib) [0x10d9c9805]
74 git_diff_find_similar + 2159 (libgit2.dylib) [0x10d9c297b]
51 similarity_measure + 784 (libgit2.dylib) [0x10d9c3804]
40 git_diff_find_similar__hashsig_for_file + 14 (libgit2.dylib) [0x10d9c20b5]
17 git_hashsig_create_fromfile + 73 (libgit2.dylib) [0x10d9bab5d]
17 git_futils_open_ro + 18 (libgit2.dylib) [0x10d9ac8d1]
17 __open + 10 (libsystem_kernel.dylib) [0x7fff93b71fca]
7 close + 10 (libsystem_kernel.dylib) [0x7fff93b72ba2]It seems to happen every time I open Xcode.
