Using newsbeuter with Tiny Tiny RSS is very slow

Compilation date/time: Dec  7 2015 04:47:17
System: Linux 4.9.11-1-ARCH (x86_64)
Compiler: g++ 5.3.0
ncurses: ncurses 6.0.20170128 (compiled with 6.0)
libcurl: libcurl/7.53.1 OpenSSL/1.0.2k zlib/1.2.8 libpsl/0.17.0 (+libicu/58.2) libssh2/1.8.0 (compiled with 7.46.0)
SQLite: 3.17.0 (compiled with 3.9.2)
libxml2: compiled with 2.9.2

Steps to reproduce the issue:

1. Set up tt-rss sync
2. Attempt to launch newsbeuter or reload
3. Wait

Other info you think is relevant:

• When I start up newsbeuter, it takes 3.5–7 seconds before I'm presented with an interface and can start reading.
• If I attempt to reload feeds, it also takes a long time. I just tested three times with time newsbeuter -x reload, and it took 102, 99 and 107 seconds.

Admittedly, my server's upload speed is slow, but in comparison, the Android ttrss-reader client opens almost instantaneously, and syncs in 0.5–3 seconds.

Well, our TT-RSS API interface hasn't significantly changed in the last 4 years—maybe we aren't using the best available ways of fetching stuff anymore.

By the way, I'd be glad if someone who actually uses Newsbeuter with TT-RSS become a maintainer of ttrss_api and ttrss_urlreader classes.
