[PD] why is midi out so slow?

i do sometimes use the ctlout object to send midi data out of pd.
but latency is very big (about 100ms)

i'm using OSS midi on ubuntu linux with vanilia pd.

using udpsend to send data to an other application that forward them to the midi out, a loop can be as small as 5ms.

(using pdreceive >/dev/midi1 on a terminal by example, see attachment)

why are the midi out objects in pd so slow, and is it possible to make them faster?
