[LLVMdev] inlining hint
...e board. Even if we did, I would still be
uncomfortable with this: "hasn't been proven entirely competitive yet"
implies that we've pursued the current inliner and tried hard to make
it better without listening to inline. In fact, the current inliner
is almost completely untuned and has many known problems.
I am concerned that "listening to inline" will paper over other things
that could be solved in much better ways. If the inlining heuristics
were already considered to be well tuned and a study showed that
'listening to inline' was better than i...

Mysql store problems
I successfully switched to using mysql and all the problems relating to sqllite
and stored configs, locking issues, etc. went away.
However, it seems as if something new has suddenly popped up in my puppetmaster
logs and the clients are failing to compile their configurations:

Building file list takes hours,how to improve performance?
Hi there,
I've backed up some files(about 20G,with many subdirectories and files) a
months ago to an USB drive,and I use rsync to check if there are
changes.After the process,I checked the log file and found no update
needed.But the stats said:
Number of files: 61775
Number of files transferred: 0
Total file size: 24169314260 bytes
Total transferred file size: 0 bytes
Literal data: 0 bytes

Performance problem with file > 2Gb
Hello,
I've setup an Samba 3 server on a Debian Etch 4
The server has :
- 8x 500Gb raid 5 via 3ware Raid Controller
- Filesystem is Ext3 over Lvm2 (I know that be better an Xfs FS instead
... now I can't change it easily )
- Xeon dual core 2
- 2Gb of RAM

Higher mono bitrate in CVS libvorbis
...so did the stereo one and -q0 in stereo was pretty much
the same size as it was in RC3. I also notice that ogginfo says that the
nominal bitrate for -q0 in CVS is 48.001000 kb/s, whereas it gives -q0 for
RC3 as 32.007000. The newly tuned 32khz modes give similar results to
this, compaired to the untuned modes of RC3.
My question is, is this intentional? I would have thought that the encoder
would have tended to hang around in the range of 2/3 of the rate of stereo,
as it has done for RC3. Just wondering if the quality settings are wrong
or whether some kind of change has been made.

must cut the line down too much for shaping to work
Hi, my situation: One internet connection 256 kbps uplink/downlink,
pretty stable speed, a Linux router with three NICs (one to ISP, one to
DMZ and one with VLANs enabled to our LAN). Each of three VLANs (1, 10,
11) is a region for me; id 1 gets guaranteed 128 kbps, id 10 and 11 both
get guaranteed 64 kbps (both uplink and downlink).
Simple configuration. After I read relevant parts of lartc

Ext3 and 3ware RAID5
...e
(256KB stripe size) with a software RAID0 stripe on top (also 256KB
chunks). bonnie++ results look like this:
mount -t ext3
175 MB/s writes, 352 MB/s reads
mount -t ext3 -o data=writeback
185 MB/s writes, 254 MB/s reads
mount -t ext2
340 MB writes, 266 MB/s reads
XFS on this hardware gets (untuned) about 300 MB/s writes and 400 MB/s
reads. The hardware itself is capable of more, and those results are
representative of several different configs of hardware and software RAID
options.
Any ideas as to what leads to ext3's performance hit? I've tested *lots*
of configurations. It&...

[LLVMdev] whole program optimization examples?
Hello,
I was wondering if there is an example list somewhere of whole program
optimizations done by LLVM based compilers?
I'm only familiar with method-level optimizations, and I'm being told wpo
can deliver many great speedups.
My language is currently staticly typed JIT based and uses the JVM, and I
want to move it over to LLVM so that I can have options where it can be

Hello,
I am planning to build a bigger Internet platform and actually evaluating
Java EE and Rails. I have a lot of Java experience and I am quite new to
Rails. After playing some weeks with Rails I am sure that it is a mature web
framework and I really like the productivtity of Rails. One of the key
advantages is that new developers will understand this platform much quicker

Some basic questions about getting the best performance for database usage
I''m new so opensolaris and very new to ZFS. In the past we have always used linux for our database backends.
So now we are looking for a new database server to give us a big performance boost, and also the possibility for scalability.
Our current database consists mainly of a huge table containing about 230 million records and a few (relatively) smaller tables (something like 13 million

Gzip compression for ZFS
Adam,
With the blog entry[1] you''ve made about gzip for ZFS, it raises
a couple of questions...
1) It would appear that a ZFS filesystem can support files of
varying compression algorithm. If a file is compressed using
method A but method B is now active, if I truncate the file
and rewrite it, is A or B used?
2) The question of whether or not to use bzip2 was raised in
the
