The HttpClient4 code in 2.5 has a bug that means it does not re-use connections; this causes it to quickly run out. However that should not cause a slowdown. > The script consists of a 'master' script that includes a 'Registration' > sampler script.

How do the average elapsed times compare? Also what about min/max std.dev? The http sampler code was re-organised for 2.5; additional classes were added and there is another code layer, but I'd be surprised if that had a significant effect. > -- > Robin D.
