Redmine

Hello,
I have a redmine instance on my server,Environment as below:
Redmine version 2.0.2.stable
Ruby version 1.8.7 (i386-mingw32)
Rails version 3.2.6
System Environment win2008r2
Database adapter MySQL 5.5.34

now I migrated the redmine system from a old server to new, same environment, so I installed ruby187 on new server and copied ruby from original server to overwrite new ruby folder(i installed to this folder), and copied redmine folder to new server(the patch same as original server), and imported the data from original server.

now I found this redmine instance running on new server very slow(the environment same as original, include install patch), and have a warning on command window as below, could you please help me on this questions? many thanks!
