Please use the windows 7 or 2008R2 "compress the whole darn drive" then benchmark. I'd love to see bottleneck scenarios on a modern multi-core (4 core or 2c4t) cpu. you'd have to create a disk image. loop: benchmark compress the whole drive benchmark restore the image since disabling compression doesn't decompress the objects. switch from HD to SSD to RAID (HD/SDD) and maybe even ramdisk. Maybe ANAND is too old for this fun - but it makes me wonder if i have a dual 6-core westmere with ESXi - 6gb SATA and SAS - i don't mind carving off a couple of cores for compression - already do for sql server 2008 (compress *.*) at a program level and why yes it is faster when used correctly (!!). Also note: you can not compress certain objects by directory in NTFS. so if you have swap or pagefile or JPEG/PR0N VIDS you could dimension this even further on the test. I think it would be a worthy ANAND article - today's compression. 1. ESXi compresses pages (ramdoubler!) before it has to swap them out since 4.1 2. many modern SAN will compress objects and deduplicate them. heck vmware does ram (ramdoubler?) and vmfs (clustered storage filesystem) deduplication at a low level already. 3. Backup Exec System Restore 2010 has the ability to send to a datastore for dedupe so those 50 pc's at work that were imaged all at once contain 90% of the same code - can be deduped. 4. SQL server since 2008 has TCP/TABLE/BACKUP compression because we have more CPU than DISK I/O. SQL server is really an os and is called SQLOS by some old times - soft-numa - etc - It must have been a good idea. This is one product microsoft can proudly call their own (best acquisition lol). Anyone think its worth the time? CPU usage would go way up but load time on constrained i/o devices (laptop 4200rpm drive) might yield more usability? or not? What about dedupe? Ramdoubler? Is it time we can afford to use those again in consumer land? I'd rather have a GC process compress stale objects then page them to reduce pagefile wear or prevent paging completely. I can't afford more than 8GB for a personal pc right yet. Inquiring minds would like to know..
