How to reduce time while deleting more than 300K records ?

Question

Hi,
I am using SQL SEVER 2008 R2. I've a doubt, if there any possible to reduce executing time while deleting  more than 3 lakhs records. I will explain about the table structure. Table_Name : test. In that table have 15 Columns , 6 Indexes ,Foreign and
Primary Key releationships. 
Query :  DELETE FROM test WHERE roleid=1      [roleid is not primary key]
Message: (308240 row(s) affected) 
Time : 28 seconds.
Cheers,

I suppose Roleid has index on it ?. 3 lac records getting deleted in 28 sec i think its ok as delete operation takes exclusive lock .Exclusive lock is not compatible with other locks so some delay might be expected 
You should check blocking process if any by using sp_who2 to see if your process is waiting on any resource or is blocked by some other SPID.
