• 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 regardless of how much memory you have)
Change vmarg.Xms=-Xms48m to ¼ of what you changed Xmx to;
e.g. if you changed vmarg.Xmx to -Xmx1024m then use vmarg.Xms=-Xms256m
NOT recommended for production / normal end users; for admins & developers only!

- 8. @cadler80 #SUTOL What makes your Notes Client START slow 12 If you‘re not on at least 9.0.1 yet 9.0.1 is a significant improvement • Pre-loading the client might also be recommended EOM of IBM Lotus products • http://www-01.ibm.com/software/lotus/support/lifecycle/
- 9. @cadler80 #SUTOL What makes your Notes Client START slow (Continued) 13 ~50% of the entire data volume in the Data directory changes on a DAILY basis in most setups • 5 - 10% in Dataworkspace ( up to 300 files) • DISABLE Antivirus scanning for at least *.ns* *.ndk *.xml *.properties in Data Directory.
- 10. @cadler80 #SUTOL What makes your Notes Client START slow (Continued) 14 Client crashes/database fixups • especially bad for network based data directories clients Outdated Hardware • You need >1-2 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 • Again, see http://bit.ly/ACzO6Z
- 11. @cadler80 #SUTOL What makes your Notes Client START slow (Continued) 15 Outdated Data directories • Virtually 100% of all NTFs (Laptops: 90%) can be removed by • Cleaning up old Notes 4+5+6 templates • using ini:SharedDataDirectory= (also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!) Operating System • Windows 7 boots ~40% faster than XP • Windows 8.1 ~55% faster than XP • ~20% faster than Windows 7, supposedly
- 12. @cadler80 #SUTOL What makes your Notes Client START slow - ODS 16 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/O This helps with ANY client AND server hardware
- 13. @cadler80 #SUTOL What makes your Notes Client START slow – ODS (Continued) 17 CAUTION: The ODS is not automatically updated when upgrading clients • Except for names.nsf, bookmark.nsf, and desktop*.dsk/ndk – IF – you upgrade properly (think ini:Setup/TemplateSetup=) • 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
- 14. @cadler80 #SUTOL What makes your Notes Client START slow – ODS (Continued) 18 Impact examples • Startup time of a Notes 8.5.3 client with 3 ODS 20 apps in Notes data = 10 seconds • After ODS upgrade: 2 seconds • Reduced File I/O of your disks/SAN/NAS after ODS 41 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
- 16. @cadler80 #SUTOL What makes your Notes Client START fast 20 Eclipse Framework Performance Improvement • Speeds up starting the IBM Notes client up to 65 % • ONLY usable in virtual environments (e. g. Citrix XenApp, etc.) • ONLY usable with a IBM Notes Roaming Solution
- 17. @cadler80 #SUTOL What makes your Notes Client START fast 21 Example: Configuration of an IBM Notes 9.0.1 FP3 Client 1. With a non-admin user (OS + Notes) run an initial setup of the Notes client. 2. Start the Notes client 3 times then wait for 2-3minutes each 3. Shutdown the Notes client 4. Create the following directory c:ProgramDataIBMNotesDataCommon 5. Copy the workspace directory from %LocalAppData%IBMNotesData to c:ProgramDataIBMNotesDataCommon 6. Delete the following files/directories out of c:ProgramDataIBMNotesDataCommonworkspace a. UDM b. Logs all but .prov2install c. cache if available d. .metadata.pluginscom.ibm.collaboration.* e. .metadata.pluginscom.ibm.rcp.personality.framework f. .metadata.pluginscom.ibm.rcp.security.auth 7. Change the parameter “jvm.shareclasses.loc=“ in “c:Program Files x86) IBMNotesframeworkrcpdeployjvm.properties” a. from “${rcp.data}/.config/org.eclipse.osgi“ b. to “c:/temp/xpdplat”

- 20. @cadler80 #SUTOL What makes your Notes Client PERFORM slow 24 ODS of databases (again) Hardware (again) 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 = latency/bandwidth limitation)
- 21. @cadler80 #SUTOL What makes your Notes Client PERFORM slow (Continued) 25 Port settings are included in the notes.ini • Type / Active / Encryption / Compression / Timeout Bad idea • 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 your Servers!
- 22. @cadler80 #SUTOL What makes your Notes Client PERFORM slow (Continued) 26 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

- 25. @cadler80 #SUTOL Performance Measuring - Client Clocking 29 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
- 26. @cadler80 #SUTOL Performance Measuring - Client Clocking (Continued) 30 Client_Clock=1 leads to a debug file of the following format:

- 29. @cadler80 #SUTOL Performance Tuning – Understanding cache.ndk 33 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 (since 2001 I've had to delete my cache.ndk only once(!)) • Let's look at some detailed traffic analysis for just ONE application (the mail file) of ONE user ...
- 30. @cadler80 #SUTOL Performance Tuning – Understanding cache.ndk (Continued) 34 100 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
- 32. @cadler80 #SUTOL Summary - A Performance Boost for your IBM Notes Client 36 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
- 33. @cadler80 #SUTOL The end is near ... 37 Spending 45 minutes on Performance Improvements can be compared to a walk on the tip of the iceberg.
