vivado 2013.3 's debug core is different from vivado 2013.2's ?
with 2013.3 : create_debug_port u_ila_0 probe
with 2013.2: create_debug_port u_ila_0 PROBE
lowercase in 2013.3 , upcase in 2013.2 ?
I test my three cases , I also found 2013.3's timing results are worse than 2013.2's. Did anybody has the same result with me ?

Yes, I noticed this as well: in 2013.3 the ILA port names (clk, probe) are now lower-case.
I think this is related to the implementation of a corporate guideline for common naming of Xilinx IP.
Regarding your performance: this is a known issue. 2014.1 will have a lot of improvement in this area.
What you could try in the meantime is disable the advanced trigger feature.

My three cases are all run in vivado tcl mode with the same tcl scripts .
The timing results of vivado 2013.3's are all worse than the timing results of vivado2013.2's.
