@zwaldowski a lot, but the benefit is larger the less contiguous the data is. Try dispatch_write()ing one with 100MB in 100 byte chunks. -
.
@tapbot_paul many of the apparently Foundation improvements are actually from CoreOS though. Way faster locks and dispatch data helps us :D -
.
@tapbot_paul certain combinations of arguments to -isEqualToString: are 1.2x and 3x faster respectively -
.
@tapbot_paul some more boring ones: CF collection copying functions do retain-if-immutable, 1-element index paths <10 are cached… -
.
@tapbot_paul there’s a subtle one in immutable NSArrays: use a zero-length array instead of object_getIndexedIvars. +~10% on indexed access -
.
@tapbot_paul oh, there’s a dedicated subclass for single-element immutable NSSets now. Cuts the footprint of those by 2/3s. -
Fun iOS 9 tidbit: NSNumbers with floating point values that have exact integer representations are also tagged pointers now
