What JDK are you using?  IIRC, the JDK's HttpUrlConnection class has
defaulted to persistent HTTP connections since at least JDK 1.1 days.

Another problem is, is it normal to httpclient to use 200ms to download a

The timing of something like this, especially on a relatively small page, is
going to be so dominated by the speed of your connection to the Internet
that "acceptable" is in the eyes of the beholder.  Is it fast enough for
your requirements?  If so, it doesn't matter which technology you choose --
they both work.  Is it too slow?  Then it doesn't matter which technology
you choose -- they both fail to meet your needs.  Is your average need to
download multiple megabytes instead of a couple hundred kbytes?  Then the
test you ran is totally meaningless because it did not reflect your real
requirements.

Any help will be great appreciated
