Some performance questions with ZFS/NFS/DNLC at snv_48
...to 2-4 linux frontends running Apache (with local raid0
mod_disk_cache), rsync (looking through entire debian trees every now
and then) and vsftp (not used much).
There are (at least?) two types of performance issues we''ve run into..
1. DNLC-through-ZFS doesn''t seem to listen to ncsize.
The filesystem currently has ~550k inodes and large portions of it is
frequently looked over with rsync (over nfs). mdb said ncsize was about
68k and vmstat -s said we had a hitrate of ~30%, so I set ncsize to
600k and rebooted.. Didn''t seem to change much, still seeing hitrates at

massive performance problems if transferring many small files
...ransferred. Has anyone an idea what I can tune
to avoid this annoying behaviour.
My samba server configuration:
- OS: Solaris 8
- /etc/system:
* SunOS 5 Cache Override fuer ClearCase
*
* ClearCase Vobs run out of inode tables and directory name
* lookup cache.
set maxusers=2048
set ncsize=34906
* ClearCase recommends that the size of a VOB host's block buffer
* cache about 200% of the size of the hosts largest VOB database
* file.
* Default bufhwm is 2% ud phys. memory. We try 2% of 2048Mb
set bufhwm=46080
* ClearCase MVFS-Tuning for large systems...
