I've been on a 2 week vacation to croatia so I had some cathing up to do.
First spin of some 1.3pre release rpms.
Built on Red Hat 7.3 with a small patch that alters the min/max readahead
buffers. That should fix the (read) performance issue that has been present
since the 2.4.18-27 2.4.20-8 switch.
Next step is building with the latest errata.
If you need the 1.2 rpms I suggest fetching the RPMS Axel Thimm made.
It might just be your lucky day, if you only knew.
