If your clip is around 30meg size and you use 10 Mg limit, your clip will not use the ram preload mode, and the triggering time will be longer.
How many clips do you have in your mediaset ?
Probably too many for your available RAM (512 Mg) - considering all your clips are in ram preload mode.
In this case your clips are not all the time in RAM - depending of the usage, it increases the triggering times considerably (loading and unloading clips in ram).
Yon can change the preload mode manually for each clip in the media windows (edit>info).
Set the clips that need a fast triggering in "compressed memory" (stream preload) or "uncompressed memory" (full preload, faster) mode.
And the others to "direct to disk" (stream) mode.
Or then increase the RAM of your computer...

If I have lets say contrast and saturation set to max on a layer. Whenever I change the clips in that layer it takes up to half a second to display the new clip with these effects (the clip appears at once but without contrast and saturation effect). Clips are still 512x384 (etc..)
The contrast and saturation pixel filters are achieved in software (altivec), so they can also increase the triggering time.
Indeed, for a short time, the video appears initially without the filters, it's a problem that is corrected in the version 2.
