If you own a computer which is several years old then most likely you will have noticed a performance degradation with the last few years. There are several reasons for this. First of all, if your computer uses a traditional hard drive then most likely your drive will become more and more fragmented. That means that the files on your hard drive are placed in many different locations. This fragmentation becomes even more severe if you drive is full. In that case it will be difficult for your operating system to figure out a location where to store large files without placing different bits and pieces different areas. That means that the performance of UPC is very much affected by the read performance of your hard drive.
If you own a solid state drive, on the other hand, you will not see that much degradation of performance. In fact, you don’t have to defragment a solid-state hard drive at all because random axis is pretty much as fast as sequential axis. There are no mechanical parts of have to be moved around as opposed to traditional hard drives.
So the best way to improve read speed and also to drastically reduce the boots time of UPC is to change from a traditional hard drive to a solid-state hard drive. Also, if you don’t want to spend as much money on a solid-state hard drive then you can use multiple hard drives. I would recommend to use a solid-state hard drive for installing the operating system and also for installing software which is frequently used. The traditional hard drive then is mostly used for storing data and applications which are not used as often.
Further, adding more RAM will also performance. If your computer is unable to store all of the data required to execute certain programs within its memory, it will be forced to write that on to the hard drive. This is called swap space. Since hard drives are rather slow, this will really track down performance. I would open up the task manager and check out how much memory is still available while you are running your applications. Take sure that you are running multiple applications in parallel because each application will require a specific amount of memory. Then you can gauge how much memory your computer is lacking. However, before installing additional RAM, make sure your motherboard supports that the amount of memory.
