Temp configuration

Hi All,

Seeking for your guidance on Tempdb

We have tried to optimize Tempdb is out env. Below are the ones we have taken care.

•    enabled instant file initialization
•    pre-sized the data files. All of them has same size each 90GB
•    created multiple data files of same size and same auto growth settings
•    auto growth specified in fixed sizes i.e. 500MB
•    enabled trace flag -T1118
•    Still we see I/O taking more 15 ms in SQL server Errorlog
•    No of physical cpus= 2
•    no of logical cpu count = 24

Not sure what is wrong. Can anybody share your thoughts on this?

From SQL Errorlog:
spid7s       SQL Server has encountered 3146 occurrence(s) of I/O requests taking longer than 15 seconds to complete on file [T:\SQL\TEMP\tempdb_1.mdf] in database [tempdb] (2).  The OS file handle is 0x0000000000001350.  The offset of the latest long I/O is: 0x0000033

Thanks in advance.
