New Server Slow response to server querywith Editor

I have recently upgraded to a new server and suspect that the issue is with configuration, the query size is only about 3-5k items however it is routinely taking about 10-15sec to render the below: When debugging the sql, mysql is performing the query very quickly so I believe that this issue is related to the rendering of the data. Server Side processing is enabled for this as well. Any suggestions?
