Solaris – Linux Performance

Lightweight & Complex Workloads

Complex Workloads



The S in SAMP stands for Solaris
Solaris Zones
★ Free, lightweight and easy virtualization
★ Allocate a “system” to each app instance or to each developer
★ Resources are controlled in one of three ways
• Capped Resources: Upper limit on consumption
• Guaranteed Resources: Guarantee of a minimum available
• Dedicated Resources: Resources are set aside for
★ share filesystems and network across zones
OR
★ dedicate filesystems and network to individual zones

Need Efficiency & Control?
Hypothetical Constraints & Objectives

Constraints:
 one server available
 need to host four environments:
 (2) Developers
 (1) Test environment
 (1) Production environment
Objectives:
 maximize sharing, minimize redundancy
 guarantee max. resources for production
 maximize efficiency & consistency btw. envs.

Find Hampster Wheels with DTrace
DTrace provider for PHP

“DTrace is one of those tools that makes you
wonder how you did anything without it before
you'd heard of it.

Why is it better than strace and similar tools? It's
non-invasive, fast, scriptable and extensible.”
- Wez Furlong



Performance Tuning - DEMO
DTrace provider for PHP
Which functions are being called by Drupal?
# dtrace -n function-entry'{printf(quot;called %s() in %s at
line %dnquot;,copyinstr(arg0), copyinstr(arg1), arg2)}' -q

How many times is a function called?
# dtrace -n function-entry'{@[copyinstr(arg0)] = count()}'

What's the file name and line number count:
# dtrace -n function-entry'{@[copyinstr(arg1)] =
lquantize(arg2, 0, 5000)}'



Security

 RBAC
− Assign users to roles with privileges they need
 Process Rights Management
− Run with least privileges
− E.g., not root, nosuid, noexec

Versioning & Protecting Data
ZFS snapshots & Rollback

$ zfs snapshot /data/site@31Oct

$ zfs snapshot /data/site@01Nov

- - - DEPLOY -> SMOKE-TEST -> UH-OH! - - -

$ cp .zfs/snapshot/@01Nov/Drupal_5.2/themes/mysite
./Drupal_5.2/themes
