    v15 v16  
    4646* identified that the old and the new drivers have the reversed order of latitude when writing the restart file 
    4747* Global spinup simulations over 400 years are done by using the new driver (thanks to Matt) 
     48* In spring 2021, Matt mentioned the speed of simulation by using the new driver, compared to the old one. A profiling was conducted to simulations by using new and old driver. In PARAM/run.def dt_sechiba =1200 seems responsible for most of the slowness of the new driver. The value of this parameter depends on user's need.  
     49* In summer 2021, a new ticket http://forge.ipsl.jussieu.fr/orchidee/ticket/786 was submitted concerning a problem of the new driver when using the compressed forcing file. By using the latest version of compressed forcing file CRU JRA v2.2, small modification were applied and tested. The error is fixed. But the new driver does not work with the older version of CRU JRA v2.1 due to the inconsistency between land variable and contfrac.  
     50*  
    4851 
    4952'''Useful information for the users of the new driver:''' 
     
    6568* to test the new driver in the recent version of trunk by running spinup analytic, fg1transnd and fg2nd.  
    6669   The comparisons of FG1 can be found at https://orchidas.lsce.ipsl.fr/mapper/?set=Milestone-4.1&mode=FG1 (thanks to Vlad) 
    67 * to understand why the new driver is slower than the older one, and how we can improve it.
