I'm not seeing anything particularly abnormal as far as CPU usage on the second sample on my System.
704x480->853x480 = 1% CPU Usage by XySubFilter
704x480->2560x1440 = 3% CPU Usage by XySubFilter
The first sample likely just caches well by chance.
Just to make sure, I'll have our dev double check that nothing strange is going on with second sample.

Change flush does absolutely nothing. I see the subtitle queue instantly drop to 1 as soon as the first subtitle event activates. I observe average 8% CPU usage windowed and 30% CPU (one core completely saturated) in fullscreen.
CPU: Intel Ivy Bridge M @ 2.3 GHz
GPU: Nvidia GT650M
OS: Windows 8
Regardless of my hardware, the subtitle renderer should never cause the video renderer to drop frames. If the subtitle renderer can't meet its deadlines, it should drop *subtitles* instead of causing unwatchable video.
Edit: I don't observe any performance problems when pre-scaling the subtitles to 2560x1440 using Aegisub. The example file http://www.sendspace.com/file/iybf50 plays without any issues while the original file chokes Xy.
