There are loads of things it could be.  We can't just fix it without knowing what the problem is.

You will need to monitor and investigate.  Is it running slow at specific times or randomly?  Is the server sized correctly for the number of users and volume of issues?  Is there a virus scanner hitting it?  Is the slowness happening because the CPU is maxxed out, or the memory struggling?  Is it thrashing the disks?  Are there any errors in your logs?  What have you customised? What add-ons are you using? 

Most of this usually does come back to "what are your users doing that slows it down?", and a valid answer can range from  "trying to use it on inadequate hardware" to "massive downloads it's not built for/hundreds of external connections". 

But, you need to do the analysis before you can work out an approach.

On that time I checked the services it is taking more CPU and Memory.On that time I took the Dump later it was fine with 5 to 10 Mint. then same JIRA was slow.I saw the logs I Didn't find any errors.

Ok, good on the  logs.  Now you need to look at what is causing the CPU and memory to be thrashed.  What are your users doing?  Are there lots of them doing something at the same time?  Is there something else on the machine that may be drawing resources?  Can you get a thread dump to see what the internals of JIRA are doing while it's running slowly?

A deeper analysis is required. It is not possible to drill down to the reason of the slowness with such minimal information.
