Date: 2009-05-26 00:21 Sender: kshevetskiy The problem has been fixed in fuse-2.8 branch. To get 128Kb blocks for writes your need: a) (linux < 2.6.26) or ((linux >= 2.6.26) and (fuse >= 2.8.0-pre1)) b) mount smbnetfs with '-o big_writes' option
Date: 2009-04-23 05:25 Sender: kshevetskiy The main reason for this behavior is the usage of 4Kb blocks for write requests and 128Kb blocks for reads in libfuse code.
Date: 2009-04-23 04:26 Sender: forest I notice slow upload speeds as well. Here are some sample times (copied from bug ID: 2492545): NAS -> workstation using mount.cifs: 6 minutes NAS -> workstation using smbnetfs: 6 minutes workstation -> NAS using mount.cifs: 5 minutes workstation -> NAS using smbnetfs: 21 minutes I tried running with -o max_write=131072, but it didn't help siginificantly. The workstation -> NAS time estimate went down from 21 to 20 minutes.
