The WAS1(WEAVE Archive System) is a software architecture for archiving and delivering the data releases for the WEAVE7 instrument at WHT (William Herschel Telescope). The WEAVE spectrograph will be mounted at the 4.2-m WHT telescope and will provide millions of spectra in a 5-year program, starting early 2018. The access and retrieval of information will be through its dedicated archive, the WEAVE Archive System (WAS). This will be developed and maintained at the TNG2 premises on the same island as the WHT. Its structure foresees the main axes of scalability, virtualization, and high availability. We present here the first performances on a simulated data set of 20M spectra, using different architectures and hardware choices.
