I Love Notes. Under the Hood of (IBM Lotus) Notes Clients 7 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 ... Under the Hood of (IBM Lotus) Notes Clients 8 + 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. Under the Hood of (IBM Lotus) Notes Clients 9 + what we should all be familiar with: Physical nsfs 1, 2, 3, … n (nsf) Desktop Under the Hood of (IBM Lotus) Notes Clients 10 Agenda Coming up next … Who am I? … and about panagenda Basics • A summary of what a Notes 8 client comes with Under the Hood • What makes a Notes client START slow (and what makes it faster) • What makes a Notes client PERFORM slow (and again faster) • Deep Diving • A peek under the hood of Client / Server interaction Under the Hood of (IBM Lotus) Notes Clients 11 What makes the Notes Client start slow (and how to make it faster) • If you‘re not on 8.5.3 yet. 8.5.3 is a significant improvement. (EOM 7: April 30, 2011!) • Note: preloading maybe 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 (up to 2 x longer start times) • Disable Antivirus scanning for at least *.n(s)* in Notes Data Directory. Period. almost 50% of the file 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%) Under the Hood of (IBM Lotus) Notes Clients 12 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 hell) • Old fixed disks Fragmentation Tons of startup programs/scripts – if the disk is busy like hell, 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) ... Under the Hood of (IBM Lotus) Notes Clients 13 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 Under the Hood of (IBM Lotus) Notes Clients 14 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: 15 seconds After ODS upgrade: 7 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 ;-)) Under the Hood of (IBM Lotus) Notes Clients 15 Agenda Coming up next … Who am I? … and about panagenda Basics • A summary of what a Notes 8 client comes with Under the Hood • What makes a Notes client START slow (and what makes it faster) • What makes a Notes client PERFORM slow (and again faster) • Deep Diving • A peek under the hood of Client / Server interaction Under the Hood of (IBM Lotus) Notes Clients 16 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 … Under the Hood of (IBM Lotus) Notes Clients 17 The catalog.nsf problem … ... or „the Asian connection“ User in Oslo Sends Doc|DB-Link to user in Hammerfest Unfortunately, the user in Hammerfest does not open the database from onsite server but from the one in Oslo ... or even Alesund or Bergen! Under the Hood of (IBM Lotus) Notes Clients 18 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!) Under the Hood of (IBM Lotus) Notes Clients 19 Agenda Coming up next … Who am I? … and about panagenda Basics • A summary of what a Notes 8 client comes with Under the Hood • What makes a Notes client START slow (and what makes it faster) • What makes a Notes client PERFORM slow (and again faster) • Deep Diving • A peek under the hood of Client / Server interaction Under the Hood of (IBM Lotus) Notes Clients 20 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 user; for admins & developers only! Under the Hood of (IBM Lotus) Notes Clients 21 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) Under the Hood of (IBM Lotus) Notes Clients 22 Client Clock=1 leads to a debug file of the following format: NOTE: Take a look at Notes RPC Parser on OpenNTF! Under the Hood of (IBM Lotus) Notes Clients 23 Adding to Client Clocking ... Network Latency has major impact on perceived client performance for users that (try to) work on serverside databases! Under the Hood of (IBM Lotus) Notes Clients 24 What happens when you delete cache.ndk (for just 1 database!) After deleting Cache.ndk Keeping / NOT deleting Cache.ndk 100 users = 150 MB vs. 3.7 MB (2,5%; -97,5%; +4000%) 1000 users = 1.5 GB vs. 37 MB Excluding Fileservers! Under the Hood of (IBM Lotus) Notes Clients 25 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! Under the Hood of (IBM Lotus) Notes Clients 26 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!
