I am using NEB for TS search in VASP. My system contains CO adsorbed(reactant) and dissociated (product)on 55 atoms of transition metals(Pd, Ru, Co and Ni). I am using following INCAR file.

SYSTEM = NEB-Calc

GGA = RP

NPAR = 80

LPLANE = .TRUE.

LREAL = AUTO

NSIM = 16

EDIFF = 1.0e-05

EDIFFG = -0.02

ALGO = normal

PREC = Normal ! standard precision

ENCUT = 400.0

ISMEAR = 1 

SIGMA = 0.10

ISPIN = 2

KGAMMA = .TRUE. 

ISIF = 2

NSW = 350 ! ionic steps

IBRION = 2 

ISYM = 0

LWAVE = .FALSE.

LCHARG = .FALSE.

ISTART = 0

ICHARG = 2

IALGO = 38

IMAGES = 8 

SPRING = -5.0

ICHAIN = 0

LCLIMB = .TRUE. 

MAXMOVE = 0.2 

TIMESTEP = 0.1 

LSCALAPACK = .FALSE.

Also is there any faster way to do the TS calculations?
