To be honest, I've found that most such contention is because of what is appropriately referred to as "crap code". đ
I recommend that you figure out what's beating on TempDB and fix that before you add any more files.

looks like you have the increase set to 10% - CHANGE it to be a fixed amount (multiple of 64KB - for that small log file likely a 32 MB increment would work fine. - so way to do it is change increment to 32MB then shrink it to the minimum possible and then let it increase to 128MB - this would leave some space free before growing again.
have a look at https://www.brentozar.com/blitz/blitz-result-percent-growth-use/ for info on growth - obviously increment should be adjusted to size of db - I have some db's with a data growth of 5GB (with IFI enabled) but these are multi terabyte sizes where growth happens during nightly batch window when it needs.

edit: dup post

artical does not say any thing about critaria , like the increment of datafile or log file should be once in a day or twoice in day?
like if i know 1 gb data is required per day by my datafile or log file so should I keep the increment to 500mb or 1 gb ?

I'm confused.... the log file name of your latest graphic doesn't appear to match or relate to any database names in your first graphic. You've also not said anything about how big your current TECHINTFDC database is or the largest index or heap you have. Do you have any idea how big this new database is going to get in the next year?
Also, do you know what the "IFI" that Frederico was talking about is?
