thanks for your polite reply.
resolved. im sorry. it was just too slow.
i changed order of port number at auto-port-configulation of dcm4chee.
my client(ClearCanvas) is using port "4096".
so i changed it from "104,4096,4444,11112,29000" to "4096,104,4444,11112,29000".
"4096" was moved from 2nd to 1st.
about the time which starting of retrive.(i was checking with server.log of dcm4chee)
"104,4096,4444,11112,29000" needed about 70sec
"4096,104,4444,11112,29000" needed 0sec.
but we couldn't notice this while we use Mac=OsiriX.
there must b any tips.
thx anyway.
