Francis Lam Microsoft Hong Kong Understand more on Windows 7 performance Feature enhancement when using with Win2k8 R2 Application Compability Windows 7 Deployment

Everyone wants performance – what’s new?

The rise of small notebook PCs (netbooks)

1GB RAM, modest CPU and Disk

Both enterprise and consumer usage Domain-joined machines require additional resources, which can be challenging for small notebooks

Increasing percentage of PC sales about 20M expected this year

Commonly available PCs now cover a broader spectrum of capabilities Over 400 footprint reductions across all components

Challenges : • Enabling Windows performance features to scale across the spectrum (small notebooks to high end machines) • Helping customers evaluate small notebooks PC Accelerators: Make the computer more consistently responsive SuperFetch ™ Works with kernel memory manager to optimize memory usage ReadyBoost™ optional flash supplement to memory

System Assessment: Evaluate performance of system components Windows Experience Index Performance Control Panel with summary scores Windows System Assessment Tests Detailed metrics underneath the summary score Handle wider range of CPUs, new DX10 graphics, plus new Disk storage (both SSD and HDD) SuperFetch What it does : Memory manager service Pays attention to user usage patterns Prioritizes pages so most important aren’t paged out of memory Pre-loads the most relevant pages into memory Make the computer more responsive by decreasing paging from disk Where SuperFetch helps Optimizing pages to user’s actual usage patterns Speeds up resume after standby/hibernate Compensating for slower disk, limited RAM Random reads Where SuperFetch does not make a big impact Day 1 scenarios (SuperFetch learns over time) Unpredictable usage patterns Systems with very fast disks Systems with very low memory Since it takes memory to manage memory, SuperFetch will throttle back if the system is very memory-constrained. (ReadyBoost still available)

When workloads cannot fit into DRAM, SuperFetch can utilize supplemental ReadyBoost caches Keep more relevant pages in memory, pull fewer from disk System is more consistently responsive Benefits are workload dependent – if the workload is large relative to available memory, ReadyBoost can help Low-RAM, slow-disk systems, like small notebooks Help resume from standby and hibernate Not boot ReadyBoost options: Internal and external ReadyBoost devices As in Vista , external devices can be : USB keys, SD or SDHC cards, Compact Flash cards

Choosing a ReadyBoost device: Size before speed RB cache should be 2-4x DRAM size (recommend 4x) More ReadyBoost caches Vista supported only 1 per machine, W7 supports 8/machine

Larger ReadyBoost caches Vista supported max 4gb per cache, W7 supports 32GB/cache FAT32 limited to 4GB per cache (filesize) exFAT and NTFS cache files can be large exFAT recommended, more suitable for removable devices Higher encryption Vista only supported 128 AES W7 supports AES 256 as an option default still 128

OEM options to configure internal ReadyBoost Can turn off compression or encryption for internal ReadyBoost devices to minimize CPU load and increase performance SuperFetch Let SuperFetch handle the tuning ; do not turn the service off Adapts based on Disk speed and available memory Turning off SuperFetch disables ReadyBoot and ReadyBoost Boot times would be much slower without ReadyBoot ReadyBoost If your machines have limited RAM (compared to their workloads) or slow disks, consider adding ReadyBoost devices. Small notebooks : limited RAM, modest CPU and disks Older machines Easy to add external devices post-purchase If customer is ordering machines, they can request internal or external ReadyBoost devices
