Slow read NETCDF4
Added by Neeldip Barman over 3 years ago
Hi,
I am getting very slow read speeds with NETCDF4 files of WRF. Simple calculations with cdo are taking hours now which was not the case with classic files, making CDO almost unusable now. Is there any way to speed up the read? Read speeds hover around 5-10 MB/s. Please help.
Thanks!

Hi,
The problem got solved.
I was using precompiled binaries of cdo in ubuntu, don't know the exact issue was but I used to get errors with hdf5.
I compiled cdo from source and the issue went away.
Thanks.
