3,123 files is not a large number. From a CentOS 4 file server here..... [root@pachyderm sky_data]# ls|wc -l 13526 [root@pachyderm sky_data]# cd ../motse [root@pachyderm motse]# ls |wc -l 28218 [root@pachyderm motse]#cd [root@pachyderm ~]# du -s /var/lib/pgsql 556420596 /var/lib/pgsql [root@pachyderm ~]# (Yeah, 556GB in PostgreSQL....) Pachyderm = 'The elephant never forgets....' But I'm not looking forward to converting it to a post-C4 PostgreSQL.... Performance on this box is pretty good, all things considered. Large log files I have found can be performance problems; check to make sure log files are being rolled properly. There are some specific MySQL tuning documents out there; I seem to remember a posting on a local LUG list about some serious MySQL performance issues that took a long time to ferret out, but I can't seem to find it quickly..... _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
