[HPDD-discuss] Bad performance with g++ compiler

Hello, I use lustre 2.7.0. When I compile a tool in C++ language (configure, make, make install). The compilation time on the Lustre is 28min. But the same compilation on a local disk or a NFS volume (Ext4 file system) the time is about 8min. I tried to change the stripe count without any succes. I did some tests with the dd commande. I have a bandwidth about 120 Mb/s How can I do to improve the compilations on Lustre files system ? Regars David
