Dear Experts,
Need you advise.

One of my database has auto growth by 1 MB.
so my doubt is,
Will frequent file growths result in CPU bottleneck.

If I had to change the auto growth setting what value should I go with.

Thanks,
Javeed.

Take a look at Kimberly Tripp's article here: http://www.sqlskills.com/blogs/kimberly/transaction-log-vlfs-too-many-or-too-few/

You don't want to have too many VLF's (which will slow down performance) and you don't want to have VLF's that are too big (because a VLF can be cleared only if none of the log records in it are needed). That article, and the links from there give you lot of useful advice.

You are very welcome - glad to help.

By the way, all of that info is about log files. For data files, you should estimate the space it will need and simply allocate the space in advance, so it won't have to autogrow.

Yes,Iam monitoring the database growth for that.
That should help me in setting a auto grow value.

What autogrowth value to use is dependent upon the database size and the expected growth. We initially set ours to 512MB for the data files and 256MB for the tlog and then adjust up as necessary.
