Standard value for performance monitoring

Guys,

I am looking into performance monitoring in the RWB bacause I think our production server is too slow. I get an average processing time per message around 60 sec, +/- 30 sec depending on the volume going through. This is obviously an unexceptable value...

But I was wondering, are there standards set for these values to indicate when performance is too (s)low? Any reference docs available from SAP?

Thanks
