Poller is slower since upgrade to Cacti 0.8.6h

I upgraded from Cacti 0.8.6g to 0.8.6h today and I noticed that the CACTID poller runs slower. Before I upgraded, it would take between 3.1 and 4.7 seconds for the poller to run. Now it takes atleast 7 seconds and quite a few times it'll jup to 12 - 19 seconds and then go back to 7 seconds. What should I look at to see what is taking longer?

I thought you where going to say like 4:23 to 5:30.... You are talking seconds here....

Have you updated cactid yet?

Yeah, I know I'm only talking seconds here and I'm probably thinking about it too much, but it was at a constant time before the upgrade. I just thought that upgrading would be faster or more stable since it uses the snmpbulkget. Now the times will spike for no apparent reason because the load average stays about the same. As I start to add more devices to cacti and more items to poll, it only seems to me that it's going to get worse.

I believe that I'm running Cactid 0.8.6e. Are there any improvements in newer versions? I can try upgrading that in the next day or two.

I've noticed that cmd.php in 0.8.6h is slower as well. When running 0.8.6g my poller times were 20-25 seconds now after upgrading polling times are 75-85 seconds.

Both you guys, I need the following information on Cactid:

Polling Host:
Number of Processors
Amount of Memory
MIBDIRS Env Variable
MIBS Env Variable

Cactid:
Concurrent Processes
Threads
PHP Script Servers
Max OID Get Size

Polling:
# SNMP Polls
# Script Polls
# Script Server Polls

Just completed an upgrade from 0.8.6f to 0.8.6h and experiencing the same problems with both cmd.php and cactid. When the poller runs, CPU rockets upto 85% and stays at this level until the poller completes (the php process takes up the majority of CPU). In my case neither cmd.php or cactid now completes within the 300 seconds.

Polling host:
CPU: 1.8Ghz (single processor)
Memory: 1Gb

Cactid:
Concurrent processes: 1
Threads: 3
PHP Script servers: 1

I'd gladly pass on more information, if someone could let me know how to get number of SNMP polls, script polls, MIBS Env Variable etc. According to the poller cache I have 544 items, and 2034 items in the SNMP cache.
