We all know and love tempdb and its sometime excessive usage, right?
I wish to know if there are any performance issues with manually setting tempdb to a large size directly, even if it is never going to utilize all the space inside?
I have a dedicated tempdb disk on 500GB. If I split up my tempdb to 4 data files and 1 log file, with a total amount of, let's say, 200GB. Will this affect performance in a negative way (if tempdb never uses all the space) ?? I mean, I have the disk space and don't use it for anything else, so that is not an issue. I just want to cover my basis that it is a good idea or not? Will tempdb reads/writes be slower when it has a huge empty datafile?
I have searched the internet already but it's always a question on how to shrink too big tempdb etc...
Thanks
