Logos 4 got so sluggish nowadays that almost I can't use it.
Is my computer the culprit or the Logos 4?
AMD Phenom X4 9650 Quad core process, Win 7, 8 gig. 64 gig SSD.
what seems to be the problem?
It appears your computer has plenty of muscle, but I have read about earlier SSD having performance issues after a while. It affects smaller capacity SSDs more than larger ones and Samsung controllers seem to be really bad.
Are you running the current Logos Beta?
Hi Bokman,
you may want to try some of the ideas here in this wiki page: Speeding up Logos 4 responses
Also take a look at this wiki page: Logos Running Slowly
It's not a beta.
It seems taking some time, about 5 minutes, to be ready fully after the initial opening of the program.
I got "not responding" messages then; now it works ok.
I guess it might be the cause that I have the library in other hard drive. I moved the Logos library fold from C drive to other drive to give some room to 64 SSD C drive.
Wiki has Mac Troubleshooting => Slow Performance includes:
May 2009 SSD performance article => http://www.computerworld.com/s/article/9132668/Analysis_SSD_performance_is_a_slowdown_inevitable_
Noted CPU was introduced on 27 Mar 2008 => http://www.cpu-world.com/CPUs/K10/AMD-Phenom%20X4%209650%20-%20HD9650WCJ4BGH%20%28HD9650WCGHBOX%29.html
Looking at a CPU intensive benchmark comparison, appears AMD Phenom X4 9650 is a tad faster than Logos 4 recommended system => http://www.tomshardware.com/charts/desktop-cpu-charts-q3-2008/Linux-Gzip,842.html
Currently Logos 4 is a 32 bit application; personally downloaded free RAMDisk software and configured a 640 MB R: RAM Disk for temporary file use by my Windows 7 standard user. After changing user environment variables (TEMP and TMP), Logos 4 searches are now writing temporary files to RAM instead of disk; RAMDisk configuration includes writing to/from disk when restarting computer so temporary files have persistence across reboots.
Note: my RAM disk has 112 MB of files after several months of use. Also tend to have ~3 GB of RAM used as cache by 64 bit Windows 7 on a laptop with 8 GB of RAM installed.
Likewise partitioned my hard drive so the fastest partition has custom Logos 4 installation and Windows 7 page file => http://community.logos.com/forums/p/24555/295852.aspx#295852
Keep Smiling [:)]
Brother toughski,
Thanks you for sharing a great tip for making Logos 4 running faster.
I'll try it.
By the way, what RAMDisk software do you use?
Any recommendation?
Thanks in advance.
Thanks Brother Toughski!
I have installed it and it seems working great and Logos 4 hasn't show sings of sluggishness yet though I have my computer running overnight. Usually, when my computer stays running overnight or waken up from sleep, Logos 4 becomes very unresponsive. But this morning it works fine.
If anyone experiences sluggishness of Logos 4, try RamDisk software. It might be the answer till Logos team does something to solve the problem.
Glad to read RAMDisk improved Logos 4 responsiveness.[8-|]
After looking at my Temp usage, changed my RAMDisk size to 324 MB along with deleting Temp contents.
Not sure how to do this KS4J.
Would you mind giving very specific steps to setting up your RAM Disk? I am running Win7-64 with 8GB RAM
I have installed RAMDisk, but am not sure how to proceed. The instructions seem to be conflicting in some parts... use this feature but not if you intend to do this....
If I run RAM Disk and create a RAM disk and tell it to create a TEMP directory, how does this work on an unformatted partition? Do I need to create a disk, format to NTFS, create a TEMP directory and modify the user variables to point to that directory? I get a bit lost in there...
Do I need to create a disk, format to NTFS, create a TEMP directory and modify the user variables to point to that directory?
Essentially yes. After creating disk, also assigned drive letter (R:) along with formatting NTFS (to match format of my Windows 7 partitions).
Personally using two accounts on Windows 7: administrative and standard. I used the administrative account to: create RAM disk, assign drive letter (e.g. R:), format NTFS, create a folder on my R: drive with standard user name, and verify/change folder permissions so standard user can folder.
For RAM Disk, have chosen to save contents when shutting down and load them during startup (autosave is unchecked). After creating folder in R: drive, restarted computer to check R: drive operation, including folder being available after restart. Note: needed to save disk image first before could check load image at startup.
As my standard user, created Temp directory within my R: drive user folder, then changed environment variables using Windows 7 Control Panel for User Accounts.
By the way, personally learned a RAM Disk of 320 MB is adequate for normal Logos 4 use, but is too small for completely rebuilding my library index. To allow rebuild index to complete, changed environment variables to use C: drive. After indexing done (bit over 3 hours later), closed Logos 4, then changed environment variables back to R: path.
Sounds like your RamDisk solution avoided the littering of Logos temp files on your SSD that your SSD garbage collection process cannot catchup with.
Solid State Disk (SSD) has finite capacity for changing bits so avoiding temporary file writes and deletes effectively extends SSD usable life. SSD controllers spread file writes to level flash memory wear in SSD.
I have installed this program. To get it to work with L4 do I need to do anything special? You mentioned changing the TEMP and TMP variables? Can you give me a few details for setting this up so that it speeds up L4? I appreciate your help!
