Hi everyone,

let me explain the case, I am totally new in umbraco field and started new working project at development environment,

I modify alot and install many packges and then uninstall them, any how one day became the content tree extremly slow and sometimes not coming at all but an error instead saying timeout error,

I extent sql connection timeout to 100 but still it is not the solution because it is slow, we have many umbraco websites on the same server and only my site has content tree problem

I restore my local db to an earlier one and my local umbraco works fine without problem but I did the same on the sql server and restore to the same point but still so slow

any suggestion:( I give up after 10 days;(

An error occured Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding. Exception Details System.Data.SqlClient.SqlException: Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
