LiveCycle Designer ES performance becomes poor

Question

Hi,
It is very strange that, every time I put a little more content in form design, the performance of ES will become very poor.
I'm using Windows 7 and ES version 8.1.2.3337.1.509884.
For example, a print form whose size is only 1074KB (16652 lines of XML ) will lead to ES becoming the largest comsumer of system resources: up-to 25% of the CPU and 121,872K memory according to Windows task manager. System even got hung if I try to switch to XML Source. 
Is it normal? Any suggestions will be appreciated.

Hi Paul,
Thanks for reply.
Test 1: save the form as xdp file.
>>>>
Size: 1084KB.
Test2: click on the XML tab and scroll through the file
>>>>
I even can not scroll down the file as the computer kept hung.
I open it with an text editor and yes, there're huge number of duplicated line as below
----clip----
  <border presence="hidden">
                              <?templateDesigner StyleID aped0?>
                              <?templateDesigner StyleID aped0?>
                              <?templateDesigner StyleID aped0?>
                              <?templateDesigner StyleID aped0?>
----clap----
On every place for border settings.
There're total 11856 occurrences for " <?templateDesigner StyleID aped0?>" in this XML, which in total has 16864 lines. Kinda creazy.
After replacing all of them with " ", the XDP size shrinks into 653KB and the XML Source could be viewed normally in Lifecycle.
For me this looks like a SW bug.
