Chris's SQL Blog

SQL Server Consultant and Exceptional DBA Awards 2011 Finalist with extensive experience in the financial, health and retail sectors. I’m extremely strong in all areas of SQL Server and specialise in Security but really get my kicks from System Optimisation and Performance Tuning. Being a DBA is a thankless task at times but sadly I do enjoy it. Any spare time I have (when not playing rugby, football, cricket, in the gym or spending time with the family) I’m trying to help out others via social network sites such as the #sqlhelp hastag on Twitter (follow me @billysassage),www.sqlservercentral.com (ChrisTaylor) or by attending and contributing to the UK SQL User Groups (www.sqlserverfaq.com) held in Manchester and Leeds.

Poll: – Index Rebuild / Defrag, what page count filter do you set?

After reviewing a number of clients overnight index defrag / rebuild scripts over the years, I’m intrigued to know how many of us actually set the page count filter when capturing the fragmentation levels.

I know there’s a lot of debate around the value to set and personally I set mine to 100, mainly because (in most circumstances) the client has no requirement for a separate update statistics job and therefore its down to the autostats update (if we’ve determined its required to be on) or indeed the overnight index defrag/rebuild job to rebuild them and even though 10000 pages isn’t a great deal on some systems for the stats to be out of date, as a rule of thumb I’d rather play it safe and defrag/update stats on tables with pages > 100.

So, interested to see what everyone sets and if enough interest I’ll blog the results :)

I’d appreciate any comments to supplement your selection too….
