VTE w/ new patch makes skip frame (feel slow) when type..

[Jeremy Messenger]

Hello,

I can type very fast and I hold down key like down or up pretty often for 
PR. With the new patch of VTE that has been added looks like this:

files/patch-src_vte.c:
=======================================
[...]

-#define VTE_CHILD_INPUT_PRIORITY	G_PRIORITY_DEFAULT_IDLE
+#define VTE_CHILD_INPUT_PRIORITY	G_PRIORITY_LOW

[...]

-#define VTE_COALESCE_TIMEOUT		2
+#define VTE_COALESCE_TIMEOUT		50
=======================================

This cause the type 'feel like' slow, but itself is faster than before in 
the benchmark (below). I am not sure what's right word for it but it's 
almost like game or video frame per sec. However, with this patch; it 
skips the frame that make it fee like slow. If I remove above patch and it 
feels much more smoother and faster. So... I decided to try to change from 
50 to 25/15 and it works a lot better!

Benchmark:
=======================================
$ time ls -R /usr/ports

With above patch:
	13.91 real	0.24 user	1.13 sys
	hold 'a' key and skip frame like at the every three 'a'; it feels slower.

With above patch and 50 -> 25:
	13.91 real	0.33 user	1.04 sys
	hold 'a' key and no skip frame; it feels smoother and faster.

With above patch and 50 -> 15:
	14.08 real	0.28 user	1.08 sys
	hold 'a' key and no skip frame; it feels smoother and faster.

Without above patch:
	21.89 real	0.28 user	1.12 sys
	hold 'a' key and no skip frame; it feels smoother and faster.
=======================================

So far, I think 15 is the better number to use because it feels more 
smoother and faster. Also, that include in the real benchmark is still 
fast. Can anyone test the default one from offical ports tree then try 
this patch (vte.diff) in attach?

Off point, I played with the benchmark:
=======================================
$ time ls -R /usr/ports

aterm: 3.40 real	0.47 user	1.23 sys
xterm: 6.47 real	0.34 user	1.38 sys
gnome: 13.91 real	0.33 user	1.04 sys
=======================================

Cheers,
Mezz
