If it only starts after 5 hours, it won’t be Latency issues – it will more likely be related to your laptop overheating slightly.
Check in power settings that the processor cooling is set to “Active” and not “Passive” – this will mean that the laptop will increase the fan speed rather than slowing the clock speed of the processor in order to cool it down. Of course, if you are running it really hard then it will overheat anyway – Generally things slowing down is a sign that you aren’t far away from an automated shutdown… My laptop shuts itself down once the processor hits 100 degrees C – which is really high (Don’t ask how I know lol…)
My laptop is fine for the majority of DJing – but if I am going to be doing a really intensive set (or DJing in a really hot room) then I will put my laptop on a cooling stand..
Try making sure that everything in the background is turned off – nothing that you don’t need whilst DJing (Antivirus, WiFi, Bluetooth etc..)
I use control panel to check what is running on my laptop to identify what I can disable.. Also download a tool called C-Cleaner which will tidy up all the windows files on your laptop and generally make it run better. It also gives you the option to control what opens on startup – which I believe the task manager in Win 7 doesn’t..
