Nothing can't say without knowing anything. Performance is huge part.

I would like to start you to compare both 2005 & 2008 servers in all the angle like H/W(64,32,...), memory(awe,...),Disk,dbsize,fragmentation ....big list..

There's no magical configuration setting that will fix poor performance.

Did you move from sql server 2005 to sql server 2008 ?

Are you doing routine maintenance of the Server ? if you are doing this whats are the step ?

SELECT ST.TEXT,SP.SPID,WAITTIME,LASTWAITTYPE,CPU,PHYSICAL_IO,STATUS,HOSTNAME,PROGRAM_NAME,CMD,LOGINAME FROM SYS.SYSPROCESSES SP

CROSS APPLY SYS.DM_EXEC_SQL_TEXT(SP.SQL_HANDLE) ST

WHERE STATUS !='SLEEPING'

ORDER BY CPU DESC

apply this query when your database is responding slow and poor performance then you will see which query is taking time and eating resources as well
