OK, I seem to be converging on something here, but I don't know what
to do with it. Shark gives me the following tree:
97.6% 97.6% mach_kernel memcmp
0.0% 94.3% mach_kernel vfs_addname
0.0% 94.3% mach_kernel hfs_create_attr_btree
0.0% 94.3% mach_kernel BTIterateRecords
0.0% 94.3% mach_kernel hfs_create_attr_btree
0.0% 94.3% mach_kernel MacToVFSError
0.0% 94.3% mach_kernel VNOP_READDIR
0.0% 94.3% mach_kernel getdirentries
0.0% 94.3% mach_kernel unix_syscall
0.0% 94.3% mach_kernel shandler
and under gdb when I break, python is in getdirentries(). (This
could also indicate my problem with the bash tab-completion.)
I am not aware of any other symptoms that would indicate a speed
problem with the file system. Any ideas on where I should go from here?
Thanks
