- DimitriK’s (dim) Weblog : MySQL Performance: 8.0-dev Progress..
As you already know, a new MySQL-8.0 milestone release is available (and
hope you did not miss all the news coming from MySQL
Server Team site – starting by what’s
new article and followed by many others (and you’ll see yet more to
There are also many good changes improving overall
MySQL 8.0 Performance. However to see a real boost on OLTP workloads
you’ll need to have little bit more of patience.. — we’re attacking
InnoDB fundamentals.. — the parts of design which are probably remained
mostly unchanged since InnoDB creation ;-)) — you can easily understand
that such a work has a long road from idea/ prototype to a final
release.. On the same time our “Preview” results are looking very
encouraging, and I’ll be happy to say you more about during my talk
@PerconaLive, 27/Apr 1:50pm :
give you a first idea about what is coming, I’ll post here a singe
“teaser” graph about a pure UPDATE performance on 22cores-HT (1CPU
socket), then 44cores-HT server (2CPU sockets (kind of today’s
“commodity” HW ;-)) — the graph is taken from the results comparing
MySQL 5.7 vs current 8.0 vs 8.0-dev (which is yet in dev progress), but
instead of TPS/QPS you can see here just levels about InnoDB internal
help you little bit to find the diff within these graphs, in short :
- yes, log_sys contention is gone in MySQL 8.0-dev 😉
- and log_write too..
- and trx_sys..
- and lock_sys..
If it’s saying you something, you could already get a first idea about
what kind of TPS boost you may expect and what kind of possibilities it
opens.. 😉 — but if not, don’t worry.. — I’ll tell you all this during
my talk in 2 weeks 😉
(yes, slides will be published, no worry;
and yes, this article will be also updated with more details)
then, stay tuned.. ;-))
And THANK YOU for using MySQL !!!
