Die Seite gibt aber auch keine Antwort über die Cache Size (nur über den ReadAhead Buffer). Im RedBook SG245393 ("Inside OS/2 Warp Server for e-business") in Kapitel 4.3.7 steht:
Buffer Cache:
The size of the buffer cache is configurable and is limited by the amount of virtual memory that can be allocated to the kernel. This limit is approximately 1GB. The JFS cache is designed to support a cache of up to 2 GB.
Note:
The default JFS cache size is 12.5 percent of the system's physical memory size. To change the JFS default cache size from its default value, edit the JFS.IFS statement found in CONFIG.SYS to read:
DEVICE=C:OS2JFS.IFS /CACHE:(XX) /AUTOCHECK:D
where XX is the size in kilobytes and D: is the JFS volume.
So weit die Theorie...
Was passiert, wenn Du die EInstellung mit CacheJFS vornimmst?
