WebUI is very slow

Hi everyone!

I have been using librenms since a year ago, I have more than 600 devices/ports and the WebUI is too slow when you open the dashboard or when we want to search some device and change to an another page, it takes like 3 or 4 minutes to do something and it is really annoying.

at the beggining i had the server on a virtual machine and then I moved it to a server with these specs but through the weeks it has the same behavior.

cpu model:
Intel(R) Xeon(R) CPU X5660 @ 2.80GHz

memory ram:

   total        used        free      shared  buff/cache   available
  32903180     1617052    25508820       34840     5777308    30774340

this the output of ./validate.php

This is more a sysadmin question. You should have the local server setup in LibreNMS, check the metrics it creates to see if you can see what might be causing it, I.e High load, high CPU, disk IO, etc.
