Page generation times are mostly a function of single core performance of the Apache/PHP thread and the sequential MySQL queries.
Generally we recommend that WebUI/MySQL/RRDcached are run on systems with faster individual cores, rather than large numbers of cores.
Polling benefits more from greater core counts, but page generation is almost entirely dependent upon the maximum single thread speed.
The most recent rolling version has some changes to caching queries to save a decent amount cache generation time.

Please make and attach additional information about the device:
- full snmp dump from device:
snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -ObentxU <hostname> .1 > myagent.snmpwalksnmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalkIf device not support SNMP version 2c, replace -v2c with -v1.
- If you have problems with discovery or poller processes, please do and attach these debugs:
./discovery.php -d -h <device>./poller.php -d -h <device>
- additionally attach device and/or vendor specific MIB files

I recommend install APCu php extension for fast caching in memory (but this is not exactly for speedup page load in your case):

I not see which Observium version you use, try update to latest Rolling revision (we already done some improve for page loads on latest revisions).
