There are a lot of talks around new coming Ubuntu 6.06, so I decided to make quick benchmarks.
I used sysbench 0.4.6 oltp-read-only workload with 1000000 rows against InnoDB and MyISAM tables.
Such workload is CPU-bound and allows to compare CPU / OS if we are using the same version of MySQL.
So I used MySQL 5.0.22 and my box Dual Core Athlon 3800+, 1Gb of RAM.
For comparison I tested the same workload on my primary Suse 10.0.

Here are results (in transactions per sec, more is better):

InnoDB
threads Ubuntu 6.06 Suse 10.0 Suse/ Ubuntu ratio
1 478.66 536.91 1.12
4 870.50 816.27 0.94
16 582.57 639.05 1.10
64 522.04 547.07 1.05
256 344.30 357.09 1.04
MyISAM
threads Ubuntu 6.06 Suse 10.0 Suse / Ubuntu ration
1 466.13 429.89 0.92
4 765.19 863.23 1.13
16 509.32 537.67 1.06
64 495.97 516.00 1.04
256 339.01 346.65 1.02

In general Suse 10.0 looks better, though the difference is not significant.

  • I appologize for offtopic :) I tried sysbench with it’s oltp test – 1st time ran with 10 concurent threads on 10K record table (by default), 2nd time – 100 threads on 100M records, the result was only 30% slower 2nd time, how’s that colud be?
    /* original idea was to check the performance of myisam vs innodb :) /*

    I recommend to run sysbench in such mode, for CPU-bound (10K records):
    1. warmup ~3-5 min (–max-time=180 –max-requests=0)
    2. several runs by 1-2 min – and than take average or maximum result

    for 100M records you need much more warmup (about 15min) and longer runs – 5-10 min each.

    Comparison results on cold database makes no sense.
