I have a pretty simple setup.  We have two NiFi servers on different networks, and they need to transfer data between them.  I have site to site set up and working using HTTPS, but for some reason it seems like every single file transfer takes a minimum of 15 seconds.   A 1 byte file will take barely over 15000ms, at a transfer rate of a couple hundred bytes per second, or a much larger file will transfer in just under 30 seconds, at a transfer rate of about 85MB/s.  I'm guessing the actual transfer of the file is happening quickly, but the transfer speed takes into account the 15 second handshake....or whetever the process is that is taking 15 seconds each time.   I looked around and couldn't find anyone else experiencing quite the same thing.   I have tried using RAW instead of HTTPS, but I haven't found a working setup for that yet--every time I try I end up with the "Magic Header not found" message.   Here are some snippets of my config files, let me know if there is anything obviously wrong.  A suggestion for how exactly to set up a RAW connector would be appreciated as well, since I've heard those have better performance anyway.     Server A: # Site to Site properties nifi.remote.input.host=$localhostname (not a variable, my superiors are just paranoid about sharing too much information) nifi.remote.input.secure=true nifi.remote.input.socket.port=443 nifi.remote.input.http.enabled=true nifi.remote.input.http.transaction.ttl=30 sec nifi.remote.contents.cache.expiration=30 secs nifi.web.https.host=$localhost IP nifi.web.https.port=8443 nifi.web.https.network.interface.default= nifi.web.https.application.protocols=http/1.1 nifi.web.jetty.working.directory=./work/jetty nifi.web.jetty.threads=200 nifi.web.max.header.size=16 KB nifi.web.proxy.context.path= nifi.web.proxy.host= nifi.web.max.content.size= nifi.web.max.requests.per.second=30000 nifi.web.max.access.token.requests.per.second=25 nifi.web.request.timeout=60 secs nifi.web.request.ip.whitelist=$server b IP nifi.web.should.send.server.version=true nifi.web.request.log.format=%{client}a - %u %t "%r" %s %O "%{Referer}i" "%{User-Agent}i" Server B: # Site to Site properties nifi.remote.input.host= nifi.remote.input.secure=true nifi.remote.input.socket.port=443 nifi.remote.input.http.enabled=true nifi.remote.input.http.transaction.ttl=30 sec nifi.remote.contents.cache.expiration=30 secs nifi.web.https.host= nifi.web.https.port=8443 nifi.web.https.network.interface.default= nifi.web.https.application.protocols=http/1.1 nifi.web.jetty.working.directory=./work/jetty nifi.web.jetty.threads=200 nifi.web.max.header.size=16 KB nifi.web.proxy.context.path= nifi.web.proxy.host= nifi.web.max.content.size= nifi.web.max.requests.per.second=30000 nifi.web.max.access.token.requests.per.second=25 nifi.web.request.timeout=600 secs nifi.web.request.ip.whitelist=$Server A IP nifi.web.should.send.server.version=true nifi.web.request.log.format=%{client}a - %u %t "%r" %s %O "%{Referer}i" "%{User-Agent}i"   ...
