my web application is getting very slow

Question

hi sir/ mam

 

i have web application which is hosted in shared server and i'm accessing the database of dedicated server  using my web application, but the processing speed of application becomes very slow.

 

if i use same web application of shared sever and access the shared server database then it will work fine with good speed, but if i access the dedicated server database then it will become slow.

 

even i increased the ram,processing speed and everything still it is same issue.

 

please help me to fix this issue
