Hackers,
I ran into this issue while setting up a performance testing environment
with MySQL 5.6/MyISAM tables. I have an arbitrarily sized test table,
in this case with a base number of rows over 1 million. When I insert
new rows into this table with super-smack, and the on disk table file is
full (Data_free=0 in SHOW TABLE STATUS;), I see an average queries per
second of around 1500-1600. If I then delete a subset of the table's
rows, reboot the test environment, and rerun my super-smack inserts,
I'll see an average qps of 8000 until the table fills up again. In this
second state, the on-disk MyISAM table file is not full, ie, Data_free
is some non-zero value as reported by SHOW TABLE STATUS;. I'm assuming
mysqld is just seeking to a spot and writing in this case vs whatever
append operation has to be done by the OS when there's no more space in
the table file.
I'm not entirely sure where the problem lies, but I've tried this with
SU+J, SU, a MD device, async, noatime, etc and have not found a way to
speed up the case where I'm appending to the table file. I've also
tried dumping indexes from the table to make sure they were not
interfering, no change. I have ktraces showing mysqld doing the same
number of pwrite operations for my test inserts when the table file is
full vs not.
The test system is running 9-STABLE from last week, and is an 8 core,
dual package Xeon with 24GB ram, an LSI 9260-8i with two volumes, one
raid1, one raid6 both using Raptor 300's. I'm aware of raid6's write
speed issues, but the limiting factor here does not appear to be the
card or the disks/arrays based on how well it performs in the "fast"
case.
I've started to look at DTrace to maybe help diagnose the problem but I
still have to learn enough of it to be useful and I can't seem to get
mysql56-server to compile with DTrace. The kernel is GENERIC with
DTRACE hooks added.
I'd appreciate any help you guys and gals can offer.
Thanks,
Nick
