Make Your Data Work for You

Let‘s start with some numbers

9 3/1/2017

IBM Notes 9.0.1 Fix Pack 7 Interim Fix 2

3/1/2017

~35.000 files (Notes 6/7 | 8/9 Basic used to have ~550) = +6.300%• 28.600 files in Notes Program\framework in 2.700 subdirectories

– 11.200 (largely undocumented) .properties files– 1.200 .jar files– 1.300 .html files

• 600 files in Notes Data\workspace in 250 subdirectories– 40 (largely undocumented) XML files– 40 (largely undocumented) .properties files

• Which is– 35.000 files in 2.950 subdirectories– 11.280 largely undocumented files

– ... and around 60 NSFs/NTFs– ... and the good old notes.ini file

10

IBM Notes 9.0.1 Fix Pack 7 Interim Fix 2 (cont.)

3/1/2017

Add over 80 preference/dialog boxes• Each dialog has ~15 settings at average

For a total of 1,200+ settings sprayed across• address book (very few)• notes.ini (few)• and XML files (lots)

Plus any plugins, widgets,add-ons, etc. “you“ or the usermay have added to the Notesclient install

What makes the Notes Client START slow

14 3/1/2017

IBM Notes release

3/1/2017

If you‘re not on at least 9.0.1 yet 9.0.1 is a significant improvement

Software lifecycle of IBM Collaboration Solutions– http://www-01.ibm.com/software/support/collaboration/lifecycle/

15

Antivirus realtime scanning in Data directory

3/1/2017

~50% of the entire data volume in the Data directory changes on a DAILY basis in most setups• 5 - 10% in Data\workspace (up to 300 files)• DISABLE Antivirus scanning for at least

*.ns**.ndk*.xml*.properties*.jar

in Data Directory.

16

What makes the Notes Client START slow (cont.)

3/1/2017

Client crashes/database fixups• especially bad for network based data directories clients

Outdated Hardware• You need >2 GB memory if you want to use Notes AND something else• Old fixed disks with fragmentation• Fun Exercise: Buy a Solid State Disk and make Notes start off of that ;-)

Tons of startup programs/scripts launching during the “boot storm”• If the disk is unable to keep up, it‘s not Notes' fault

17

What makes the Notes Client START slow (cont.)

3/1/2017

Outdated Data directories• Virtually 100% of all NTFs (Laptops: 90%) can be removed by• Cleaning up old Notes 4+5+6/7 templates• using ini:SharedDataDirectory= (also with Single User install!)

Operating System• Windows 8.1 boots ~20% faster than Windows 7• Windows 10 ~15% faster than 8.1

18

ODS of local databases

3/1/2017

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 & 9• ODS 52 = Notes 9.0.1

The difference between ODS 43 and 52 = up to 80% LESS FILE I/OThis helps with ANY client AND server hardware

19

ODS of local databases (cont.)

3/1/2017

CAUTION: The ODS is not automatically updated when upgrading clients– ODS 51 requires Notes >= 8.5 and CREATE_R85_DATABASES=1 in notes.ini for NEW db's– ODS 52 requires Notes >= 9.0.1 and CREATE_R9_DATABASES=1 in notes.ini for NEW db's

Good News for Notes > 8.5– Use NSF_UpdateODS=1 with CREATE_R85/9_DATABASES=1 for a one-time upgrade of most local

databases• NOTE: USE WITH EXTREME CARE IF YOUR DATA DIRECTORIES ARE ON A NETWORK DRIVE!• NOTE: End users can't access databases during compact OR databases will be ignored if in use

20

ODS of local databases (cont.)

3/1/2017

Impact examples– Startup time of a Notes 9.0.1 client with 3 ODS20 databases in Notes data = 45 seconds– After ODS upgrade: 17 seconds– Reduced File I/O of your disks/SAN/NAS after ODS41 to 52 upgrade by 60%– Removing 70% of all old files in Data directories on SAN/NAS = 45% less managed storage (backup)

The bad news: There is no way to tell what is “out there”– 3rd party tools or random inspections are highly recommended

21

IBM helps!

What makes the Notes Client START (super) fast

23 3/1/2017

Eclipse Workspace improvement

3/1/2017

• Every IBM Notes Client start in a virtual environment (citrix, vmware, etc.) is a first (setup) start and takes at least 23 sec on average

• ~65% - 70% of time during first starts is used to build the workspace folder (at least 15 sec)

• A typical new workspace folder (IBM Notes 9.0.1 FP7)consists of– >500 files– >200 folders– >85 MB (including 64MB *xpdplat_.jvm_G11 file NotesShareClasses improvement)

Building the workspace folder causes lots of file I/O

24

Eclipse Workspace improvement (cont.)

3/1/2017

Accelerate the IBM Notes Client start to be >65% faster (with less file I/O)

1. With a non-admin user (Windows + IBM Notes) run an initial setup of IBM Notes2. Start IBM Notes and wait for 2-3minutes3. Exit IBM Notes4. Start IBM Notes again and wait for 2-3minutes5. Exit IBM Notes6. Create the following folder %ProgramData%\IBM\Notes\Data\Common7. Copy the workspace folder from %LocalAppData%\IBM\Notes\Data

to %ProgramData%\IBM\Notes\Data\Common

25

Eclipse Workspace improvement (cont.)

8. Delete the following files & folders in %ProgramData%\IBM\Notes\Data\Common\workspacea. UDMb. Logs all but .prov2installc. .metadata\.plugins\com.ibm.collaboration.*d. .metadata\.plugins\com.ibm.rcp.personality.frameworke. .metadata\.plugins\com.ibm.rcp.security.authf. .metadata\.plugins\com.ibm.rcp.managedsettings

What makes the Notes Client PERFORM slow

What makes the Notes Client PERFORM slow

3/1/2017

Again• ODS of local databases• Hardware

Notes.ini• EXTMGR_ADDINS = (not just) local virus scanners• Disable Notes “plugins“ like virus scanners etc.

– They increase Network traffic by up to 200 – 250%!

Data directory on the network vs. fixed disk• Disk performance is the #1 bottleneck

– think SSD vs. normal HDD ; 7.200rpm vs. 5.400rpm ; network drive vs. local fixed disk

29

Port settings

3/1/2017

Port settings are included in the notes.ini• Type / Active / Encryption / Compression / Timeout

Legacy• LAN0 / COMx / DisabledPorts should be removed

Good idea• Use TCPIP according to the client type• PORTS = TCPIP• TCPIP = TCP,0,15,0,,12320, Desktops• TCPIP = TCP,0,15,0,,45088, Laptops• TCPIP = TCP,0,15,0,,12288, Citrix / VDI• Riverbed !?

Don‘t forget the Domino servers!

30

What makes the Notes Client PERFORM slow (cont.)

3/1/2017

Install types: Basic vs. Standard– Basic client starts up fast, Standard client, well … not so fast

IBM Roaming Users– Try replicating 80MB each time you logon to Notes before use!

Connection documents– Pointing to outdated server names or IP addresses– Low priority connection documents, which can cause connectivity failures

Location documents– IP addresses for mailserver breaks Policies– Outdated mail and home server information– Outdated mail file path– Outdated Catalog server

PERFORMANCE Tips and Tricks

32 3/1/2017

Performance Measuring with Client Clocking

3/1/2017

NOTE: All of this should only be done on “ONE” client – slows down client, creates huge log files!

Use the following to see and measure client performance– CLIENT_CLOCK=1– CONSOLE_LOG_ENABLED=1– Debug_Outfile=c:\debug.txt– Debug_Console=1– DEBUG_TCP_ALL=1 (use only if needed)

Fileserver or local disk Performance Debugging is virtually impossible– If on >= 8.5 try adding DEBUGGINGWCTENABLED=16386 in Notes

33

Performance Measuring with Client Clocking (cont.)

3/1/2017

Client_Clock=1 leads to a debug file of the following format:

Performance Tuning – Understanding cache.ndk

3/1/2017

We've all been “advised to”/guilty of deleting the cache.ndk in an effort to cure Notes performance problems/symptoms

– Some companies even delete cache.ndk on a scheduled basis

HOWEVER, let us explain the impact of that on Notes performance ...– Increases traffic between client and server by 4,000% (forty times more traffic, yes)

(10,000+% if the data directory is on a network drive)– The more databases end users use, the worse it gets– There is always a root cause – deleting cache.ndk only fixes symptoms– Let's look at some detailed traffic analysis for just ONE application (the mail file) of ONE user ...

37

Performance Tuning – Understanding cache.ndk (cont.)

3/1/201738

100 users =150 MB vs. 3,7 MB

1000 users =1.5 GB vs. 37 MB

Excluding Fileservers!

After deleting cache.ndk Keeping / NOT deleting cache.ndk

Summary

Summary: IBM Notes Performance Boost - Reloaded

3/1/2017

Update/clean out your ODS, databases and templates and hardware

Standardize whenever and however possible– This will save you hugely on support time/cost

Keep your users version/fix packs current– Each release brings performance improvements but also resource demands

Work around your inability to see clients– Write an inventory agent, login script, get a 3rd party tool

Any challenge can be overcome with Knowledge and Tools– All client issues are solvable
