Tool : Vivado 15.2
Vivado takes more time for synthesize,implementaion, and wrie bitstream in my PC.
Is there any possible reason for this?
Thanks and regards,

MAke sure you have sufficient free memory on machine when running Vivado:
The below link is the FPGA memory recommendations using Vivado:

Which OS are you using?
Make sure you are using supported OS. Refer to this link page 9 for supported OS:
Try to close all other programs and check if it is taking same amount of time.
Is it looking for nodelocked or floating license? It might be taking time to search through many locations for license. Set the XILINXD_LICENSE_FILE variable to the location where license is located.
Select "Clear Cache" from the "Manage Licenses" tab in Vivado License Manager.
Check if servers are working properly.
Try running with Flow_RuntimeOptimized synthesis setting in Vivado.
Let me know if this helps.

Any update on this post? If it is Large design consisting of complex loops then high runtime are expected.
As suggested you can try using RuntimeOptimized for implementation as well which will run less iterations to reduce the runtime but this comes at an expense of phys_opt_design disabled.
