Description

JOSM defaults to 3 simultaneous connections per hostname. Most modern browsers default to 6 or more:

​http://www.browserscope.org/?category=network&v=top

In

/src/org/openstreetmap/josm/gui/layer/WMSLayer.java

    public static final IntegerProperty THREAD_LIMIT = new IntegerProperty(PREFERENCE_PREFIX + "simultaneousConnections", 3);

should be changed to

    public static final IntegerProperty THREAD_LIMIT = new IntegerProperty(PREFERENCE_PREFIX + "simultaneousConnections", 6);

WMS is not a typical HTTP request. It usually requires quite intensive processing on server side to get specified request. My guess is, that instead of more simultaneus connections, it is better just to request bigger tiles. But this really depends on your screen size / network speed.

I personally use WMS tile size of 1024, but I usually work with 2560x1440 screen. So my guess is that's hard to come with rational default.
