SharePoint Best Practices Chat with Spencer Harbar

Background:

I met Spencer Harbar (SharePoint MVP) at the 2009 MVP Summit.  My friend AC introduced us.  Spencer and Andrew both recently spoke at the European SharePoint Best Practices Conference. Spencer was kind enough to take a few minutes to chat about his slide deck he made available.  The following is a transcript of our conversation:

dbottjer says:

ok, so for SSP's

your saying that a common myth is that the SSP should be on a deadicated box?

even in a load balanced situation

I've always done what I think you’re suggesting which is place on all web front ends.

Is that correct?

Spence says:

yeah

so that's basically what i am saying

you have no choice but for the SSP Admin site to run on all WFEs

because it's a regular Web App

it's not possible to have it on a specific box

dbottjer says:

ok, can you explain the statement “…placement of DCs is far more important instead of one dc for every three WFE.”

what do you mean by placement?

Spence says:

so this is how "far away" DCs are from the SP Farm

in other words you need a DC on the same subnet as the SP boxes

dbottjer says:

ok

Spence says:

and forget about the whole 1 DC per 3 WFEs

don't get me wrong

if you have a heavy use SP Farm then you *MAY* need additional DCs

but as a general rule of thumb, there is no rule of thumb

dbottjer says:

So that recommendation is like a you can't go wrong with 1 DC for every 3 WFE but it is the no thought approach.

Spence says:

yup

it's bad advise

because often those machines end up doing nothing

dbottjer says:

how do you test stuff like that

Spence says:

stick it in a lab

and also measure in production

dbottjer says:

What tools to measure?

Spence says:

lsas.sys had a bunch of perf counters

authN requests a second and all that type of stuff

plus the usual CPU, Network, Vmem etc

dbottjer says:

so the magic number thing

This is something I've looked at myself

so take the 2000 items per folder

Spence says:

i feel a nightmare coming on

dbottjer says:

there nothing coded into SharePoint that says you can't go beyond it's just a guideline.

Spence says:

correct

dbottjer says:

but seems like 2000 comes up often

Spence says:

2k is the point where the performance of the *default view* begins to suffer

dbottjer says:

l2k is like a sweet spot and the default view is the key

Spence says:

as having 2k items displayed in a grid is really daft (in any platform)

yup

dbottjer says:

and it really has to do with iteration correct?

Spence says:

yup

that code is a managed wrapped for a COM component

u can have way more than 2k items in a list

it's just the view that causes problems

which is basically the same as if u had a asp.net form displaying 2k items from a DB on one page

without paging etc

 

Conclusion

Spencer I would like to again thank you for taking the time to answer my questions.  I hope others will benefit from this posting of our chat. 

Thanks,

Dennis
