[NFS-Ganesha-Devel] nfs_rpc_process_request spends 150 seconds

In Windows nfs client, nfs_rpc_process_request(lookup/readdir etc) sometimes takes more than 150 seconds(v3_full). I think this is weird, because 150 seconds too long. Is anyone know what's going on during the period? Thanks in advance. Ganesha server info ganesha version: V2.7.6 FSAL : In housenfs client info nfs version : nfs v3 client info : Windows server 2012
