 Speeding up Logos’ responses

Is Logos running unacceptably slowly for you? Some people have experienced this. Here are some suggestions which together should improve the performance dramatically. Try them in no particular order, depending on what is easiest for you.


Some tweaks in Logos

These tweaks have been identified which have improved performance for people who have had performance issues despite perfectly good hardware.
  • Opening fewer resources at same time is faster and more effective for Bible Study + Learning Logos has becoming proficient tip
  • Logos blog has tip about collapsing guide section(s) for speed improvement
  • Forum PAINFUL SCROLLING ... has an Exegetical Guide tweak – remove Word by Word section for faster scrolling. Workaround option: in New Testament, displaying Louw-Nida numbers scrolls faster – plus hovering mouse on Louw-Nida # has English gloss pop-up containing semantic domain information. Visual filters can highlight greek morphology in interlinear Bibles.
  • Speeding up Logos responses has many more Logos usage tweaks.
  • If you don’t think you’ll need Logos’s Internet features (PowerPointSermons.com, SermonAudio.com, SermonCentral.com; sermons.logos.com), then set “Use Internet” to “No” in Tools > Program Settings
    • Note: You will need to close Logos and start it back up again for this change to take effect
    • Option: can customize Passage Guide to remove internet sections and have “Use Internet” set to “Yes” to sync personal information with Logos servers (online backup)
  • Turn off the visual filter for “Links to Open Panels”. This causes some performance degradation, particularly in some resources. Try turning it off in each resource and see if it makes any difference.

Disable anti-virus on-access scanning of Logos files

  • Since Logos is hard drive intensive an anti-virus (or even some backup utilities) scanning files as you use them can really slow the program down. Exempting the Logos folder from this scan in your anti-virus program can restore lost performance. Please note that not all AV programs use this protection strategy, consult the help file/documentation to find out if it does and if so how to add the following exemption.
  • Windows Vista/7/8: C:\Users\<UserName>\AppData\Local\Logos4
  • Windows XP: C:\Documents and Settings\<UserName>\Local Settings\Application Data\Logos4
  • Mac OS X: Users<UserName>/Library/Application Support/Logos4

Upgrade your computer’s hardware

  • If you have less than the minimum system requirements to run Logos, then you’ll need to upgrade to more memory and/or a faster computer.
  • Even if you have the minimum requirements, upgrading to the recommended requirements would help, especially if you have lots of resources and like to work with lots of them open at once.
  • Get a faster video card; it has been noted that this makes a difference.

Some tweaks for Windows

- If you don’t have a Tablet PC, turn off the “Tablet PC Input Service” which is taking up needless CPU cycles and memory – here’s how:
  • Start > Control Panel > Administrative Tools > Services
  • Scroll down to “Tablet PC Input Services” and double-click on it (in XP this is called “Ink Services”)
  • Change Startup Type to “Disabled”
  • Close Services and restart your computer.
- Turn on some of the compatibility settings in the Logos icon – here’s how:
  • Close Logos
  • Right-click on the icon you use to start Logos (whether this be on the desktop, on your Start menu, or on your Quick Launch toolbar); you’ll need to do this in all places if you use multiple methods)
  • Select Properties
  • Click the Compatibility tab
  • (If you’re using Vista) Turn on the checkboxes for “Disable desktop composition” and “Disable display scaling on high DPI settings”
    (If you’re using XP) Turn on the checkbox for “Turn off advanced text services for this program”
  • Click OK
  • Restart Logos

- Set your pagefile size manually. A system managed size will constantly resize your page file based on demand. With the high memory demands of L4 this will cause serious performance loss. Setting a custom size page file will limit file fragmentation and consequently increase the program response.
  • Control Panel>System>Advanced>Performance Settings>Advanced>Change
  • Select a hard disk (better if not your primary disk)
  • Select Custom size and write the size of your page file
  • Set
  • After clicking ok you will have to restart your computer for these changes to take effect.
- Windows XP and Vista users may benefit from installing Automation API 3.0 (already installed in Windows 7, could be included in Vista updates)

Mac OS X tweaks

Mac Troubleshooting page has Slow Performance section. Also, Logos Support has Mac Running Slowly.
