In PEAKS 7, we have re-engineered many parts of the algorithms to make them more efficient.
"The increase in speed [of PEAKS 7] is quite remarkable."In this post, we will use an internal test to illustrate the dramatic speed improvements our users love.

Test data and search parameters
12 files generated from Thermo Q-Exactive instrument was used. Both MS and MS/MS were acquired on high resolution. In total, there are more than 100,000 MS/MS spectrum. The detail search parameters is as follow.
Test hardware and operating system
Mac mini late 2012 version. Intel i7-3720QM processor at 2.6GHz. 16GB RAM. Windows 7 Professional Edition 64 bit. The Windows OS is installed using Boot Camp.
The test and the result
PEAKS 6 and PEAKS 7 were installed on the same Mac mini computer. The computer was rebooted between analysis.
First off, we want to test our much loved de novo sequencing speed improvement and here is the result. PEAKS 7 de novo is more than five time faster!
