![]() ![]() But sadly it only confirmed what the df command saw: my disk was nearly full, and whatever 250GB I had deleted were somehow still lurking around. I thought perhaps Disk Utility would bring clarification, perhaps via a First Aid run. I double-checked on the command line with df -h, and the output corroborated the statement of the application I wanted to install: 98% disk space used. Sure enough, I finally had space again.īut when I tried to install something, which instantly told me I only had 14GB available, and that’s just not enough. I freed up about 250GB of files, emptied the trash, and checked under About this Mac – Storage. That helps keep OS X happy.I had a weird issue on y MacBook today: after being low on space for what felt like months, I bit the bullet and deleted 50% of stuff from hard disk. A utility such as C*cktail or OnyX can be used to run maintenance such as cron scripts, log rotation and clearing, cache cleaning and so forth. I can see what’s happened, so that I can open Activity Monitor and identify and quit the process.ĭon’t forget OS X maintenance. ![]() It can come in handy if an errant process gets stuck and gobbles up CPU cycles, for example. I’ve never had any problem with MenuMeters. And of course a restart once in a while will clear any cobwebs and give your RAM chips a fresh start.Īlthough I often caution against installing hacks, I use a little utility called MenuMeters that lets me see at a glance RAM and CPU usage in my menu bar. If you are running a lot of Widgets, you might be surprised by how much of your computer’s resources they can capture. If you’ve got other applications open that are memory-hungry, such as a photo editor or video editor, try freeing up RAM for DEVONthink by quitting them. Although my main database takes more than 30 seconds to load the first time (it’s default), after Quit and relaunch the application and database open in less than 8 seconds. If you’ve been running DEVONthink pretty hard, RAM can be freed up simply by quitting and relaunching the application. Remember, too, that if you’ve added a lot of new files to your drive, Spotlight can slow things down while it’s indexing the new material. Another possibility is a stuck process that’s using up the CPU, or a boatload of Widgets that tie up RAM and CPU (and sometimes network) resources. Virtual Memory is wonderful, because it allows procedures to be completed after free RAM has been exhausted – but at a price in elapsed time. That means that some of the data being processed has to move back and forth between swap files on the hard drive and RAM, which slows things down. My guess is that you are getting slower performance from DEVONthink because Virtual Memory is being used. Generally, I expect a single term Exact query to take 50 milliseconds or less. (I always run Tools > Verify & Repair before Backup & Optimize, or run Scripts > Export > Backup Archive instead). If I had run Backup & Optimize before running those searches, I would have seen a slight speedup. ![]() Note: I’ve added a number of downloads from the Web since I last ran Backup & Optimize yesterday. But I haven’t had a single pageout, and only the default 64 MB swap file, with 0 bytes used. Since I restarted yesterday I’ve also done some photo editing in Aperture, which was opened on top of the apps listed above, but is presently quit. Open applications include DT Pro Office, Safari, DEVONagent, Mail, iCal, ScanSnap Manager and System Preferences. Those were All, All Words, ignore case searches.Īt the moment, I’ve got 1,534.2 MB free RAM, plus 204.5 MB inactive RAM. Adding “fish” to that query resulted in 13 results in 2.326 seconds. A search for “methylmercury toxicity” yielded 16 results in 1.560 seconds. I just did a single-term search for SPARC (scholarly publishing and academic research coalition). I’m running it on a ModBook (a Mac tablet based on a MacBook) with 2.2 GHz Core 2 Duo CPU and 4 GB RAM. My main database is considerably larger, with 29,245,651 total words at the moment, and more than 24,000 documents. ![]()
