I upgraded startup drive to SSD from hard disk, and RAM to 16 GB from 8 GB, in an early 2011 Macbook Pro 17 inch notebook that has a 2.2 GHz quad core i7 processor. Did it myself. Apple says this model only can be upgraded to 8 GB maximum RAM, but some research showed the real max is 16 GB. I haven't had any problems since installing the 16 GB RAM last week. The SSD has 6 gigabit link speed, while the old hard disk has 3 gigabit. To preserve the life of the SSD, I turned on trim support and noatime, turned off local Time Machine snapshots, turned off sleep mode memory backup to persistent storage, and disabled sleep disk image. Speedup results, without doing anything with temp folders and ramdisk:

I am not really surprised that calibre does not convert faster as it is pretty cpu intensive and you have lots of RAM. My calibre startup time seems to be about 10 seconds (I have way too many books in there) with SATA HD and 8G RAM, so even 5% does not excite me. Nice to see some actual numbers though. Thanks Helen |

On Windows I found that using a RAM disk for temporary files helped speed thins up. I presume the same an be done on MacOS ? It also has the additional benefit of reducing wear on the SSD.

calibre uses only /tmp
On OS X, /tmp is usually a symlink pointing elsewhere. |

http://blog.alutam.com/2012/04/01/op.../#time-machine https://raw.github.com/gist/931579/1...disk_MacOSX.sh It works but doesn't speed up calibre startup or bulk conversions. Tried various ramdisk sizes. I added a line for another ramdisk for /var/folders which is where calibre conversions seem to happen on OS X. /var/folders actually mounts on ramdisk as /private/var/folders. But that didn't speed up bulk conversions either. So I commented out my extra added line. Obviously I'm missing or misunderstanding something. I'm new to command line and symlink. Is there a way with command line to figure out exactly which folders the symlink /tmp points to? Spoiler:

I'm not an OS X user so I can't help. Basically you need to find out where /tmp points to and ensure that location is mounted in RAM.

I guess I need to buy a book with discussion of temp files, symlinks, and ramdisks on OS X Mountain Lion. For now I'm not using ramdisk until I know what I'm doing. Last edited by unboggling; 10-23-2012 at 02:49 AM. |

I convert all books that I add to calibre. But I'm trying to speed up conversions with temp files on ramdisks mainly out of curiosity, not necessity.
