GUI getting sluggish on a Netgate m1n1wall 2D13
I am running pfSense 2.0.1 on a Netgate m1n1wall 2D13 router with a SanDisk SDCFH-002G flash drive installed. After a few months of operation and configuring IPSec VPN tunnels, I am noticing that the GUI is performing noticeably slower. For example, it now takes 3-4 seconds after clicking 'Apply Changes' for the next screen to appear. Do you know what might be causing these delays? The pfSense dashboard only shows that the disk is 18% full.
I am not getting any CPU usage information via SNMP (into OpenNMS) so I'm not sure exactly what the status is of the CPU usage (I only seem to be recording interface usage). 'System Activity' usually shows the system to be 60-70% idle. 'IPSec Status' shows 96 IPSec Phase 2's configured.
It's normal for things to take a while on CF. It has to remount the filesystem read/write, then write out changes, then switch it back. If you have packages installed it can add to that as well.
