Server FTP & cPanel Optimization Required

We noticed that cPanel & FTP services are acting extremely slow on our server. It took approximately 5-8 seconds to load an page in cPanel and 5-7 seconds to change a dir in FTP(Uploading speed is normal). It's strange because the sites(httpd) on our server are all loading quite fast, I have no idea why FTP & cPanel behaves slow. We are looking for a Linux / cPanel / pure-ftpd expert to fix and optimize these services. PLEASE DO NOT BID IF YOU CAN'T GRANTEE TO HAVE THIS FIXED / OPTIMIZED FOR US. We are posting this project and choosing providers seriously, SO YOU SHOULD PLACE YOUR BID SERIOUSLY AND BE RESPONSIBLE with every single command executed on our server. PS. Escrow provided upon request, funds released after fixed / optimized.
