Hello,
I've seen that CCleaner Clears the DNS Cache, why not clear the ARP cache as well?
Maybe something like this might give a hint:
Netsh Interface IP Delete ARPCache
And, why not add a Boot Optimization Defrag, that speeds up the boot up process?
This might give a hint:
defrag \ -b
Last but least, why not Process Idle Tasks, to clear the RAM?
This is might give a hint on this one:
rundll32.exe advapi32.dll,ProcessIdleTasks
Kind regards,
Vemo
