Hi,
Recently I found that format of fonts.cache-2 file are different on
32bit and 64bit system. It leads big performance issue for 32bit
applications on 32bit/64bit mixed system, like x86_64. Because 32bit
applications must re-create local cache file on startup, almost every
time.
For more information, see https://bugzilla.novell.com/show_bug.cgi?id=160226
Is it possible to unify the cache file format for both 32bit and 64bit system?
That bug is not world readable.
I designed the cache format so that it would contain caches for both
32bit and 64bit systems in the same file. It may not work; I'll look
into it tomorrow.
Fundamentally it's impossible to use the same mmapped structures for
both the 32bit and 64bit architectures, so in principle there should be
two copies of the data in the cache file.
