Clean Caches command vs recompile

Before I do performance check for stored procedure, I always clean the
caches using the following commands.
DBCC DROPCLEANBUFFERS
Go
DBCC FREEPROCCACHE
GO
But sometimes I think it's annoying as it basically purges all the caches
from the SQL server.
So if I just test one procedure's performance, I can just add 'WITH
recompile' keyword in the end, right?
is that the same thing since this way stored procedure will not use the
caches even caches exist.no, it's not the same thing. both 'with recompile' and 'dbcc freeprocbuffer'
will force recompile of the procedure, but 'dbcc dropcleanbuffers' will
purge the data cache (which is the reason it's not advisable to do it on a
production server).
