[cacti-user] Cisco CM-Stats Template: Performance Sucks

Dear Forum,

Any help would be very much appreciated. I really need to have a 
solution on this. I have been searching, reading and poking for 2 weeks 
now with no good results.

I have followed the links below to set up traffic monitor for Cisco 
class maps, which basically involves setting up the CM-Stats template:

The template works and i really appreciate the authors who worked on it.
But sorry to say that, I experience performance problem when I added 5 
routers with each having about 200 instances of graphs and data sources.

Now, I have 2 questions:

1. Can we improve on the performance of the template? As I read, the 
template uses the "Script Server" which has much worse performance than 
"normal SNMP query".

2. Or is there an alternative template with better performance?

My last resort would be to write my own template; but that is something 
i had not done before.  However, i am tempted to try.
