HANA http response for static content

Dear fellows,

  I'm experiencing a http response degradation with a newly installed HANA REV 101 system.

  The wait time for retrieving a small static css file is as high as 300~500ms, which is 10 times as big as my previous rev 93 server.

  Could anyone suggest where problem might be with my new HANA server?

Thanks and Best Regards,

Shady
