I make file transfer part that will be used IM.
but, it's speed was slow, the speed of transfer was measured about
20~30KByte in local network.
I had profiling with shark.
- 24.9% mach_kernel ml_set_interrupts_enabled
...
...
- 15.9% mach_kernel find_user_regs
...
more detail :

file transfer part is simple, like this
NSFileHandle *mSocketHandle;
...
[mSocketHandle writeData:[aPacket data]];
...
why it's so slow?
is it osx's system problem?
what can I do for speed-up?
thanks
( sorry about poor my english )
