Conclusions

Oxid, 1 box: PHP/Apache/MySQL

CPU bound from 2 clients on, MySQL Server QC wins

Oxid, 1 box: 1 vs. 10 clients absolut

Higher impact once CPU bound, MySQL Server QC wins

Oxid, 1 box: 1 vs. 10 clients relative

Relative: 200% 400%, MySQL Server QC wins

MySQLnd QC Plugin vs. Server QC

MySQLnd QC Plugin is insecureCan serve stale data

No knowledge of transactions

No knowledge of temporary tables

No knowledge of user variables

No knowledge of MERGE and stuff

No authentification

No protection of cache entries

Server QC can cache moreFor benchmarks set: cache_no_table = 1

Oxid, 1 box: theoretical maximum

Tuned with cache_no_table = 1, PHP QC w. APC wins

Thoughts on tuning

CPU bound from 2 clients onMySQL eats 1 out of 2 cores

PHP tuning irrelevant, if MySQL eats 1 core

Cache tuning is irrelevant

Goal #1: kick out MySQL!cache all queries!

cache_no_table = 1

cache_no_table = 1 = MySQL Server QC

Oxid, 1 box: 1 vs. 10 clients tuned

Tuned with cache_no_table = 1, PHP QC w. APC wins

How important is byte code caching?

Irrelevant... if your application is CPU bound

and, if you are CPU bound because of MySQL

if your application is I/O bound

and, if your are I/O bound because of MySQL

if

But you still want to use it together with QC!

Oxid, 1 box: PHP byte code caching

Byte code caching is nothing without query caching

Oxid, 1 box: BC gains (1 client)

With/without BC compared: 20% - 60% win

Oxid, 1 box: QC gains (1 client)

Without BC, with/without QC compared: 3% - 75% win

Oxid, 1 box: BC + QC gains (1 client)

With BC and QC: 3% - 120% win

Oxid, 1 box: Use QC and BC together

10 clients: performance improvements up to 180%

Query caching and your CPU

Turn on central heating in the winter

Turn off fans in summer

Oxid, 1 box: CPU bound workload

Lower MySQL CPU time in favour of PHP CPU time!

Oxid, 1 box: MySQL CPU usage

Share cache contents between PHP worker processes

Oxid, 1 box: MySQL CPU usage

Tuned (cache_no_table=1) to eliminate MySQL usage

Oxid, 1 box: goal #1 is fewer queries!

Monitor MySQLs' Com_select and Queries statistics

Oxid, 2 boxes: PHP/Apache + MySQL

PHP QC and MySQL Server QC about equal fast

Oxid, 2 boxes: 1 vs. 10 clients

Relative: 130 200%, CPU bound on PHP/Apache box

Oxid, 2 boxes: PHP/Apache + MySQL

Tuning (cache_no_table=1), theoretical maximum

Is Memcache storage slow?

Invalid benchmark setup!CPU bound: Memcache eats PHP resources

Why Memcache if using only one PHP machine?

Needs to be benchmarked with 3+ boxes

Conclusions

Performance degration with QC?

Rather not - difference is less than 1%

Which handler is best?

Check the basicsWhat is available?

Share contents among processes?

Share contents among machines?

Handler specific features, e.g. statistics

All handler seem to scale about equally well if you consider their general properties

Observations

CPU boundless MySQL means more PHP

MySQL % CPU can be reduced by factor 30!

cache as much as you can!

cache handler: start with default

cache handler: step up to APC/Memcache
