Hi all,
I worked directly with Victor to test out his patch and wanted to
report back to the mailing list on my results. I set
SPICE_KEYPRESS_DELAY=10 and saw an improvement in the response time
when I was typing. I was using Fedora 21 in the client with Gnome 3
and tried typing in LibreOffice Writer and in the Gmail web mail
client on Firefox on my Fedora 22 VM as the SPICE server. The lag is
somewhat noticeable with the keypress delay set to 100, such that when
I compare typing on a physical machine vs a SPICE session I can
definitely feel the difference. I say somewhat noticeable because it
is not a huge difference; I can just feel a lag when typing. With the
10 ms delay it felt more like real-time.
I'm wondering where to go from here. Victor did submit a patch for
the environment variable, so that will be available as a workaround
for those who know about it. I guess it is up to you the developers
if you want to make configuration or fix something more mainstream.
There were a couple complaints about it on the mailing list that I dug
up, but it doesn't sound like there's been much public outcry to fix
it. Nevertheless, since I am presenting it as an issue, I'd be happy
to do any further testing if anyone is interested in looking into it a
bit further, as I would recommend it as something that should be
addressed.
I believe I was one of those reports you dug up. I had originally
compiled in the changed delay and found the experience much more
pleasant ; nothing is broken the way it is now, but the feel is
significantly improved with the reduced latency.
I would like a configurable for this setting, and it is implemented, as
I recall, as a widget property so at least at some level it is
configurable.
The environment variable approach that's floating would work but is so
hidden that the two of us would be the only ones on the planet using
it! But aside from that, I'm all for it!
