Diagnosis before treatment. Otherwise interesting things happen.

While an SSD will speed up I/O for sure, make sure that your bottleneck
is indeed I/O before jumping to the conclusion that and SSD will help.

Do you see the disk light flicker when she feels the VM is slow? If so,
there
is a chance

You can use iotop to see which process is eating up I/O. If you don't have
that then vmstat will tell you that there is indeed heavy I/O and if it is
read
or write.
