9.5 & SQL item restore speed - WOW!

[mkretzer]

Hello,

today we upgraded to 9.5 and immediately had to restore a SQL database.

Before, we restored with ~ 60 MB/s and were never quite happy with it. But now just by upgrading to 9.5 we suddenly write with 150 - 180 MB/s.

Thanks for the great update!

Impressive indeed. Thank you so much for taking time to share these results!
I will be sure to pass your feedback along to the dev and QC folks behind this.

I am wondering if everyone could see such improvements? Is it specific to your environment or for everyone just by code changes

[Gostev]

Up to 3x for everyone, and up to 6x depending on environment (the older your versions of SQL Server and Windows OS of backup server are, the bigger is improvement). Although these ratios are in comparison to 9.0 RTM, as part of these enhancements were already included in 9.0 U2.

whats causing this speed bump? i was gooing to open a case about such a issue... sql restore eg. 60mb/s (same like direct copy of mdf/ldf files from flr folders) compared to directly assigned vmdk to a vm and copy from that disk 120mb/s....

but i will give a try for 9.5 and compare than first...
