I hate latency, so that is very much appreciated!

I found the problem, and it wasn't related to Orca. I'm running tlp (power management script), which by default sets the CPU performance governor to "powersave". When I connected my computer to AC, the lag went away. To be thorough, I disabled Braille (on battery) and still noticed the lag. Sorry for the confusion!

Hi,

Still running Orca from master, per my original post. I've attached debug output. Some of the processing times for generation are above 0.2s, is that typical? It's a small amount of time, but pretty noticeable here. Also, there appears to be an issue communicating with brltty, even though it's running, I'm in the brlapi group, and am getting Braille output. Not sure what's going on there, but I wonder if I'm missing a needed package.

Hi Justin.

Like José, I'm not seeing any sluggishness with the situation you 

describe. In fact, Orca's quite responsive for me. If you're able to 

test Orca master, that would be great. Failing that, mind capturing me a 

full debug.out so that I can see where Orca is spending extra time?

Thanks!
