Vuze downloading making CPU/disk nearly 100%

[darkfireblade25]

Whenever I download, my CPU usage and disk usage goes to upwards of 90%+ with CPU hitting 100%. I'm not even downloading to C:\ either, rather to an external. Really don't know what's happening here, looked around and didn't find any solutions.

System info:
Java 1.8.0_112 (64 bit)
 Oracle Corporation
c:\program files\vuze\jre

SWT v4508, win32
Windows 10 v10.0, amd64
V5.7.4.0/4 az3

In the Vuze change log http://wiki.vuze.com/w/ChangeLog under version 5.7.2.0 is the followin entry for a bug fix:

- Core | Fixed broken synchronization in DHT tracker causing 99% CPU usage [Parg]

perhaps it's reoccurred or maybe a problem with W10.  Are you using the latest java?

What have you tried yourself to resolve the issue? 
have you re-booted your pc?  Have you run a cleaning package acroos your system (CCleaner).  Some sites I need to use have damned advertising script that often cause similar cpu & memory utilisation problems.  My remedy for that is to use a cleaner package and ensure that file-slack and free-space are wiped. It takes roughly a minute per GB of space but it does the trick.  Just clearing browser cache does not seem to solve the problem.  If I stay clear of those sites and avoid adverting scripts that get loaded by pop-up and pop-unders, I don't have a problem.
