Comment (by leavengood):
I don't know, this feels pretty fast now, especially once files are in the
file cache. I am testing this opening a directory with 8612 empty files
that I made with touch. It takes about 8-10 seconds. I am testing Haiku in
VirtualBox with 1 CPU on a host machine with an i7 2600K and Intel SSD
from 2011. I don't know how much using a VM would taint the profile
results though.
I ran the profile command against Tracker and on the first run the "add
poses" thread (which actually is what reads from the disk) hits the
EntryCache a lot, and then after that it is really just hitting the kernel
to get stat info from the cache as well as some memory allocation.
When I close the resulting window and get the profile information there is
really not that much in Tracker itself high on the profile list. See
attached file. It is doing a whole lot of _kern_port_buffer_size_etc
calls, which maybe is just communication with app_server? Or that is the
information sent from the "add poses" thread? Either way I am not sure
what else could be tweaked in Tracker.
