Recently we’ve been considering a hardware refresh for our developer/consultant/architect laptop build (on Windows Server 2008 R2 Standard with Hyper-V). After a fair amount of deliberation we decided to pilot a new model but stumbled massively at the first hurdle: when we enabled the Hyper-V role on a new Dell Latitude E6410 we got a blue screen. Further testing revealed that the graphics driver was at fault and the SVGA driver worked fine. However, the SVGA driver only has single monitor support. Back to the drawing board.

Optimising the SharePoint 2010 IW Demo VM Part 2
Continuing on from Part 1, in this post I’ll discuss the Microsoft 2010 Information Worker Demo Exchange VM, the SahrePoint VM’s event logs and potential future improvements to the environment.
Exchange Server Reconfiguration
Tidying up the Exchange server is a much more straight-forward process. In fact, all of the changes that I made are network orientated per the network changes from the first post, so if you are not adding a second NIC or a second fixed IP address on the original internal NIC, these steps aren’t necessary.

Optimising the SharePoint 2010 IW Demo VM Part 1
Around the time that Microsoft released the public beta of SharePoint 2010 they also released a demonstration virtual machine, known as the 2010 Information Worker Virtual Machine, which was updated to RTM in mid-June. This is a fantastic resource for demonstrating SharePoint 2010. The content and demonstration scenarios (including walk-throughs) represent a huge investment from Microsoft and it would be foolish not to at least evaluate these assets. Personally, I think it’s silly to reinvent this wheel.
Now the public beta trial is expiring and people are moving to the RTM build. It appears to be much improved, in that more of the product works in this version and a few niggles have been fixed now. However, it’s widely acknowledged that the resource requirements for this virtual machine are gargantuan due to the breadth of what it offers.

SharePoint 2010 SEO Analysis with the IIS SEO Toolkit
The IIS.NET Search Engine Optimization (SEO) Toolkit provides a powerful analysis tool that can generate reports for web editors and can automatically generate sitemaps and robots.txt files as well. These reports not only provide insight in to page rank improvements but also help content editors identify missing/duplicate content and find broken links. This post provides an overview of how the tools can be used by content editors or web managers who do not have access to the server infrastructure and what you can expect to see when running an SEO Analysis against an out of the box SharePoint 2010 Publishing site. I will also review the server tools that generate sitemaps and robots.txt files.
Installing the SEO Toolkit
Although Remote Server Administration Tools can be installed on Windows Vista and Windows 7, I have produced the directions below on my Windows Server 2008 R2 desktop. The instructions should be fundamentally the same for any OS once IIS Manager is available locally, however it is installed. To be crystal clear, the SEO Toolkit can be used by anyone with Windows Vista, Windows 7, Windows Server 2008 or Windows Server 2008 R2. It is not a requirement to have access to the web server and it is not necessary to install IIS locally.

Office Web App default cache size is 100 GB
Earlier today I noticed some fairly innocuous commentary in the Features that influence the size of content databases section of the Storage and SQL Server capacity planning and configuration (SharePoint Server 2010) TechNet guidance:
“If Office Web Apps are being used, the Office Web Apps cache can significantly affect the size of a content database. By default, the Office Web Apps cache is configured to be 100 GB. For more information about the size of the Office Web Apps cache, see Manage the Office Web Apps cache.”
100 GB? Surely that can’t be right. So I followed the link and found that:
The Microsoft Word Web App and Microsoft PowerPoint Web App generate a series of images to create a rendition of a document that is viewable in the browser. If Microsoft Silverlight 3 is installed, XAML is used to create the rendition. Creating the rendition can consume large amounts of computer resources. To reduce resource consumption, the Word Web App and PowerPoint Web App store the renditions in a cache, created as part of a SharePoint content database. Renditions in the cache are then used for future requests of a view of the same document. In an environment where most documents change infrequently, but are viewed regularly, maximizing the space dedicated to the cache or the expiration period, can improve performance and reduce resource consumption. In an environment where most documents frequently change, you can optimize performance by reducing the space that is dedicated to the cache, or by reducing the time documents are stored in the cache.
So… make sure to plan SQL database disk space accordingly (nb: this is an update to the original post – I originally thought this was front-end disk space). Also note that you can pin the cache to a specific site collection’s content database. Either reduce the cache size (instructions in that link above) and adjust according to performance needs or invest in SQL storage accordingly.
And don’t forget to plunder the enormous investments Microsoft are making in SharePoint 2010 documentation. It’s the only way you’ll find out about all of these considerations.

PDF iFilter performance benchmarks, in which FoxIt performs nearly 40x better than Adobe
I’m not usually keen on re-posting other blog entries here, but I think this is quite important. Jie Li from Microsoft has been releasing some good guidance on SharePoint 2010 recently. In his most recent posts he’s been looking at FoxIt’s PDF iFilter 2.0 and comparing performance against TET and Adobe. Both TET and FoxIt are optimised for multicore processors while Adobe will only use a single CPU. This has massive performance implications. In his tests a full crawl too 13 minutes with FoxIt versus 8 hours+ with Adobe. http://blogs.msdn.com/opal/archive/2010/02/09/pdf-ifilter-test-with-sharepoint-2010.aspx

Building a SharePoint 2007/2010 development environment – Part VI: Issues and Results
In the first five parts of this series I covered the project objectives and the system design, then turned my attention to the Hyper-V host image build, automated deployment and the guest virtual machine build. In this post I review some of the questions and issues we’ve encountered after a few months of working this way and some overall reflections on the approach. read more »

The definitive word on Hyper-V high-end graphics performance
The Microsoft virtualisation team are certainly taking community engagement and transparency seriously these days. I’m happy to report that Ben Armstrong (Virtual PC Guy) has posted the definitive summary of Hyper-V high-end graphics performance issues. He was the first person to discover the issue and has produced most of the guidance on it since. Key things to note:
- It’s not an issue on processors with SLAT, but these are only just hitting the market in laptops in the near future
- It’s not an issue with the SVGA driver
- I’ve asked if the SVGA driver might ever offer multi-monitor support. He’s looking in to it. This might be a great compromise until processors with SLAT become ubiquitous
- This same problem occurs in all native Hypervisors
- Virtual PC and VMWare Workstation do not have the same problem but they are Type 2 hypervisors and do not offer the same performance as Hyper-V
So… there’s still no conclusive solution but it’s good to have the full context of the problem. For more background on why this matters for SharePoint see my previous post on the matter.

Building a SharePoint 2007/2010 development environment – Part III: Host image build and performance benchmarks
Having agreed the project objectives and designed the system, I turned my attention to the Hyper-V host image build. This is a high-level build guide with start-up time and baseline memory consumption benchmarks at key milestones. These benchmark figures were taken from the Windows Server 2008 R2 Release Candidate build and are admittedly a bit imprecise. However, they do provide an overall indication of system performance as things were added to and removed from the installation. Although I do not have precise figures on RTM improvements, I spot-checked a few of these benchmarks when I rebuilt the system on RTM. Start-up times improved slightly at each milestone. In fact, the final benchmarks came in at 100MB less idle memory used in the RTM release. read more »

Summary of Mark Russinovich’s Inside Windows 7 Redux
This Channel 9 “going deep” interview with Mark Russinovich dives very deep in to kernel changes in Windows 7 and Windows Server 2008 R2. I’ll do my best to summarise. It’s excellent stuff, illuminating:
