Subject RE: [users@httpd] Apache 2.x configuration for high load servers

> This went well until there were not too many files on the file system...

Our experience here has been this: We're on ext3 and caching (on disk) several hundred thousand
files using mod_disk_cache.  We got
worried we were going to have too many files but using "df -i" below shows we're at about
a million files on the file system so
we're only at 2% usage.

Now we did run into the 32,000 subdirectory limit that ext3 has so we modified our mod_file_cache
settings to get around this like

CacheDirLevels 2
CacheDirLength 1 

$ df -i
Filesystem            Inodes   IUsed   IFree IUse% Mounted on
VolGroup00          72712192  972739 71739453    2% /
/dev/sda1              26104      73   26031    1% /boot
tmpfs                1974407       1 1974406    1% /dev/shm
