This is normal.

[slrn sends a GROUP command for every group it's subscribed to]

Now we enter the group we want to read.

slrn requests the headers of all articles in the group. This is what
takes so long. I don't understand why slrn does this. It could
use the XOVER command instead. In fact, I just tried to reproduce
this here. My slrn (Slrn Version: 0.9.6.2 (Feb  7 2000 16:09:56) 
S-Lang Library Version: 1.2.2) uses XOVER. I couldn't find an
option to force slrn to use XOVER, but I'm not expert as I use
tin normally. Anyway, this looks more like a problem on the
client side to me.
