: Check out that you have rsize=8192 and wsize=8192, and then the

I should have mentioned that I do have rsize and wsize set to 8192 as well
as 64 Megs of physical memory (128 Megs of swap). The rest of the
networking appears to be very fast, e.g., ftp.
It's too bad that you think that it should not matter with buffered stdio
because, this newsreader (slrn) uses buffered stdio to write out the newsrc
file and, it takes twice the amount of time to perform this task to an NFS
mounted disk when slrn is run under Linux than it does under sun4 systems.
: And remember, there _is_ life after 2.0. We'll get this issue worked out
: soon enough, so don't be too worried about it.
I have no doubt about that.
