Hi All
I want to begin by stating that I have read the corresponding chapters in the SQL 2008 Internals (Kalen Delaney) book and have consulted with other resources as well.
I just want to confirm my understanding of the lazy writer process.
The lazy writer process looks after both the data cache as well as the plan cache, using different algorithms for each cache.
Is this correct?
Thanks

What do you mean by 'looks after'?
btw, first page of search results for 'lazy writer plan cache data cache'

What do you mean by 'looks after'?
When the Lazy Writer wakes up, it checks the size of the free buffer list - Does it also check the status of the plan cache?
Just read the article - Yes, the lazy writer checks the plan cache as well
I just wasn't sure if the size of the plan cache was also managed by the Lazy Writer or another process
Thanks
