Boost is still going through internal testing. It is now at RC-2. For those that have requested to Beta and have, to date, not been responded to, I will send out mailings this evening.

System stats:
- cacti 0.8.6i with updates, running thold, monitor, syslog plugins
- FC4 with latest updates only slightly tuned for performance
- mysql 4.1.20 (tuned, not out of the box)
- php 5

Machine stats:
- Desktop Dell Dimention 3000
- 2.8 P4 Single Core CPU
- 512MB (according to top only approximately 220Mb used)
- some el-cheapo 80Gb IDE Drive.

Dual Core or Multi-threaded machine seems to give significant improvement in php running time. Dual CPU would probably be even faster.

MySQL tuning seems to give significant boost in performance.

Boost. Either on your own or via contract. It's not 100% yet, but it works where I have it deployed. However, others have reported issues.

At this time, the graph menu show image with delay.(1~10 seconds)
My team mate complain to me that web is too slow to watch...:(

So, I consider upgrading memory(to 12GB) or finding bug of apache or MySQL. Because memory resource has no non-using space.

Cacti web performance is affected by how many graphs per page you have to display. Apache requests all the image at once, so if you have 100 graphs on a host it will take a bit longer than 10 to process.
If you have a lot of graph based on the same template, you can try to switch graph grouping style to "data query index" to see if there is an improvement.
You can also try to expand host in order to have one more level of depth in your tree.

I just modified my test Cacti system to poll with cactid.

System Specs:
Dual 1.3GHz PIII
3.5GB RAM
Windows Server 2003 Enterprise

Cacti Specs:
0.8.6j
Using plugin architecture
Plugins: thold, monitor, weathermap

This machine runs 4 separate cacti sites (5m poll, 1m poll, 30s poll, 10s poll) as well as GLPI, and hosts the databases for each.

CMD.PHP
02/06/2007 09:05:26 AM - SYSTEM STATS: Time:25.5670 Method:cmd.php Processes:4 Threads:N/A Hosts:28 HostsPerProcess:7 DataSources:532 RRDsProcessed:330

CACTID
02/06/2007 09:33:24 AM - SYSTEM STATS: Time:17.5608 Method:cactid Processes:2 Threads:6 Hosts:28 HostsPerProcess:14 DataSources:532 RRDsProcessed:330


I've played around with the # of procs/threads, and this seemed optimal for my setup. A savings of 8 seconds is significant when running multiple concurrent pollers, and thus makes me happy :)


Thanks, cacti!

Cwalton,

Check out the Boost plugin. Should make you very happy indeed.
