Subject: too big min_free_kbytes
Date: Mon, 24 Jan 2011 11:56:46 +0800 [thread overview]
Message-ID: <1295841406.1949.953.camel@sli10-conroe> (raw)
Hi,
With transparent huge page, min_free_kbytes is set too big.
Before:
Node 0, zone DMA32
pages free 1812
min 1424
low 1780
high 2136
scanned 0
spanned 519168
present 511496
After:
Node 0, zone DMA32
pages free 482708
min 11178
low 13972
high 16767
scanned 0
spanned 519168
present 511496
This caused different performance problems in our test. I wonder why we
set the value so big.
Thanks,
Shaohua
