[9fans] "laggy" drawterm on local network?

[Corey]

I'm on a 802.11g here on my lan in my house, where my cpu/auth server
sits - and drawterm is noticeably  slow/laggy.  For instance, mousing up/down
the rio menus, and drawing/moving new rio windows, scrolling through large
amounts of text... all produce regular finegrained intermittent delays before
"catching up"... it's just past the threshold of annoying/frustrating -
especially as I was expecting smother operation here on my lan over
relatively decent bandwidth.

Before possibly spinning my wheels attempting to fix/diagonse potential
issues on my home network/routing - I'd like to ask: is this actually normal,
or is it likely something's up w/ my network to cause such noticeable lag on
drawterm?  (I've at least done the obvious to ensure no other network traffic
is saturating my lan's pipe)

Thanks!

Oh yeah - I'm using tcp and not il.

clearly!  /dev/draw is very efficient, but graphics are being
pushed over the wire.  and since tcp is not record preserving,
a local wireless network is just the sort of thing where the
delayed ack might hurt.

i use wireless (borrowed laptop) about once a month and
don't see any issues.  perhaps you're on a busy or contended
channel?

Ah... heheh - cleary: because I'm using drawterm and drawterm
doesn't do IL? (sorry if that's a lame question)

I'd like to try IL next, just so I have some direct personal experience
with it vs. TCP.

Wow - o.k., I just went and switched my laptop off the wireless,
and connected via ethernet... and damn - huge difference: drawterm
operations are now silky smooth.

I'll now try different channels on my wifi router, see if that makes a
difference with my drawterm's performance over wireless.

Thanks!

currently, that's up to the host os.  and none of the host
oses do.  in theory one could send raw packets from dt
directly.

Of course, that makes sense - thanks!
