Howdy guys. Sorry for the crosspost. Patch to speed up taglib.

[Manuel Amador (Rudd-O)]

Interesting.

Possible test (assumes a 1GB RAM machine):

sync
echo 3 > /proc/sys/vm/drop_caches
dd if=/dev/zero of=/tmp/testfile count=1 bs=900M
cp /tmp/testfile /tmp/testfile2
(run the old taglib-test on a huge tree of files)
(check interactivity performance afterwards)

sync
echo 3 > /proc/sys/vm/drop_caches
dd if=/dev/zero of=/tmp/testfile count=1 bs=900M
cp /tmp/testfile /tmp/testfile2
(run the new taglib-test on the same tree of files)
(check interactivity performance afterweards)

The test should evict the caches and increae memory pressure.

Another test:

echo 3 > /proc/sys/vm/drop_caches
time kernel compile + time taglib-test in parallel

See which kernel compile finishes first
