Before we start ...
I Love Notes.

What the (or rather a used) Notes 8 STANDARD Client typically comes with
• > 20,000 files (Notes 6/7 used to have ~550) = +3,700%
• 17,000 files in Notes Program\framework in 1,800 subdirectories 7,500 (largely undocumented) .properties files 1,500 jar files 1,200 HTML files
• 3,000 files in Notes Data\workspace – in 2,400 subdirectories, out of which 1,850 are empty 900 (largely undocumented) XML files 100+ (largely undocumented) properties files
• That is ... 20,000 files in 4,600 subdirectories 8,500+ largely undocumented files Many (many many) subdirectories are plain empty, especially in Data\workspace
... and around 100 NSFs/NTFs (=0.5 %) ... and the good old notes.ini file ...
Meet.Share.Learn 29th & 30th March, Melbourne, Victoria, Australia
AusLUG2012
+ over 80 Preferences Dialog Boxes!
• Each dialog has ~15 settings at average
1,200+ settings sprayed across addressbook (very few), notes.ini (few), and XML files (lots)
Plus: any plugins, widgets, addons, etc. „you“ or the user may have added to the Notes client install.

What makes the Notes Client start slow (and how to make it faster)
• If you‘re not on 8.5.2 yet. 8.5.2 is a significant improvement. (EOM 7: April 30, 2011!)
• Note: preloading may be recommended – many users start Notes only once per day (=cold starts only!)
• Boot-Storm (up to 10 x longer start times)
• OS Indexing (up to 2-3 x longer start times)
• Antivirus Software
• Disable Antivirus scanning for at least *.n(s)* in Notes Data Directory. Period. almost 50% of the data volume in the entire Data directory change on a daily basis in most setups (replication, fti, checking for
background agents, ...), 8.5% in Data\workspace
• Disc encryption (up to -50%)
• Database encryption (up to -50%)
• Port/Network-Encryption (-20%)

What makes the Notes Client start slow (and how to make it faster)
• Prehistoric Hardware
• At least 1 GB – 2 GB recommended if users use more than „just“ Notes (otherwise: Swapping drama)
• Old fixed disks Fragmentation Tons of startup programs/scripts – if the disk is busy-busy-busy, it‘s not Notes‘ fault.
• Grown Data directories Virtually 100% of all NTFs (Laptops: 90%) can be removed by Cleaning up old Notes 4+5+6 templates using ini:SharedDataDirectory= (also with Single User install!)
Up to 70% of all NSFs still have an old ODS (see next slide) ...
Meet.Share.Learn 29th & 30th March, Melbourne, Victoria, Australia
AusLUG2012
ODS? What‘s that?
• ODS = On Disk Structure
• ODS 16 = Notes 2 • ODS 17 = Notes 3 • ODS 20 = Notes 4 (or templates) • ODS 41 = Notes 5 • ODS 43 = Notes 6 & 7 • ODS 48 = Notes 8 • ODS 51 = Notes 8.5
• The difference between ODS 43 and 51 = up to 80% LESS FILE I/O; average 50% less.
Also helps with slow local fixed disks, not just SAN/NAS! – Think servers, too!
• Unfortunately the ODS is not automatically updated when upgrading clients
• Except for names.nsf, bookmark.nsf, and desktop*.dsk/ndk (provided you upgraded „properly“ ... uh-oh) • Upgrade to ODS 48 requires Notes >= 8 and CREATE_R8_DATABASES=1 in notes.ini • Upgrade to ODS 51 requires Notes >= 8.5 and CREATE_R85_DATABASES=1 in notes.ini
Meet.Share.Learn 29th & 30th March, Melbourne, Victoria, Australia
AusLUG2012
ODS continued
• Fortunately, in Notes 8.5 you can use
• NSF_UpdateODS=1 • This will do a one-time upgrade of all local databases in the background
• USE WITH EXTREME CARE IF YOUR DATA DIRECTORIES ARE ON A NETWORK DRIVE! Loadbalance!
• Note that end users cannot access databases during compact (mailfile replicas!) • Note that names.nsf and bookmark.nsf are upgraded at next client startup ( Splash screen)
• Impact examples Startup time of a Notes 8.5.2 client with three ODS 20 databases in Notes data: 10 seconds
After ODS upgrade: 2 seconds After upgrade of all NSFs from previously mostly ODS 41 to 51 = 60% less File I/O on SAN/NAS! Removing 70% of all old files in Data directories on SAN/NAS = 45% less managed storage (backup)
• Unfortunately, you have little to no clue on „what is out there“ = which databases where and with which ODS
(we can help with that – after this session ;-))

What makes a Notes Client PERFORM slow (or badly/wrong) It doesn‘t get any easier ...
ODS of databases (again) Hardware (again) Install types (Basic vs. Standard, Data directory on Network vs. fixed disk) • Desktop, Laptop, Citrix, local, network, „XP User/Roaming Profile“ Notes.ini and Network (more later)
• Port-Settings (e.g. compression) – not turned on in many companies, or worse: turned off on server, on on client … • EXTMGR_ADDINS = (not just) Local Virus Scanners
Disable Notes „plugins“ like Norton or McAfee – they increase Network traffic by 200 – 250%! Connection documents Locations • Mail-/Homeserver, path to mailfile (Alarming!)
• Catalogserver (otherwise Homeserver)
Catalog.nsf on Home- or Catalogserver …
Meet.Share.Learn 29th & 30th March, Melbourne, Victoria, Australia
AusLUG2012
The catalog.nsf problem … ... or „the Asian connection“
User in Cairns Sends Doc|DB-Link to user in Melbourne Unfortunately, the user in Melbourne does not open the database from onsite server but from the one in Cairns ... er even Albany *ouch*
Meet.Share.Learn 29th & 30th March, Melbourne, Victoria, Australia
AusLUG2012
More of what makes a Notes Client PERFORM slow (or badly/wrong) The 95+5% problem ... or why Managers often don‘t like IBM Lotus Notes as much as they could / should
90-95% work „somehow“
• Training, Helpdesk, IT skilled end users, ... • Still huge Potential for cost savings (e.g. 80% less helpdesk calls) The remaining 5-10%, however, require 75+% of all subsequent efforts (manual / individual)
• E.g. sending a Notes 8 upgrade package to all clients fixing all „problem“-clients requires 75% of the entire project time & efforts
NOTE: Virtually 100% of all VIPs are part of the „5-10%“
High frustration on Management-Level High willingness to Migrate
(away from Notes; not originally to another product!)

Widly unknown² How to speed up your Notes client for daily working – for Admins/Developers only!
• Search for the file jvm.properties underneath [LotusNotesProgramDir]\framework\rcp
Open it in a text editor
• First line to look for is: vmarg.Xmx=-Xmx256m
• Change it to e.g. vmarg.Xmx=-Xmx1024m (Maximum is ½ of physical memory; do NOT change it to more than 1024m irregardless of how much memory you have)
• Change vmarg.Xms=-Xms48m to ¼ of what you changed Xmx to; e.g. is you changed vmarg.Xmx to -Xmx1024m then use vmarg.Xms=-Xms256m
• NOT recommended for production / normal end users; for admins & developers only!

Deep Diving: Client Clocking
CLIENT_CLOCK=1 CONSOLE_LOG_ENABLED=1 Debug_Outfile=c:\debug.txt Debug_Console=1 ;DEBUG_TCP_ALL=1 (use only if needed) Fileserver/local disk Performance Debugging is a pain / not possible, really; (try DEBUGGINGWCTENABLED=16386 in Notes >= 8.5)
Meet.Share.Learn 29th & 30th March, Melbourne, Victoria, Australia
AusLUG2012
Client Clock=1 leads to a debug file of the following format:
NOTE: Take a look at Notes RPC Parser on OpenNTF Also, see http://www.domiclipse.com/domiclipse/web.nsf/d6plinks/FRUX-7L5ULC

What happens when you delete cache.ndk (for just 1 database!)
100 users = 150 MB vs. 3.7 MB (2,5%; -97,5%; +4000%)
1000 users = 1.5 GB vs. 37 MB
Excluding Fileservers!

Adding to Client Clocking ...
Network Latency has major impact
on perceived client performance for users that (try to) work on serverside databases!
Meet.Share.Learn 29th & 30th March, Melbourne, Victoria, Australia
AusLUG2012
Latency times and their meaning for end users Response times turn into painful delivery times:
• „# RPC Calls * (Latency Up + Latency Down)
• 30 Calls * (60 + 60) = 3.600 ms!

Summary
• Configurability and connectivity are both a – if not the – major strength and weakness of LN/D
• Weaknesses can be cured with Knowledge and Tools
• The < the knowledge, the more important the tool(s) • don‘t just reinstall • don‘t give up • if you fight for the Notes client,
it will pay you back with much more than just email (*hint*) • Every symptom has a root cause – cure the root cause, not just symptoms!

Timeout
Spending 60 minutes on Performance Improvements
can be compared to a walk on the tip of the iceberg –
we have worked on a MANY more business cases
and solved a MANY more problems than those mentioned just now.
If your problem was not mentioned in this session –
be it a Client, Server, Design, Admin or other challenge:
we would love to hear from you.
