Thanks everyone for your help.
I have 4GB RAM on Windows 7 laptop. Probably not enough I guess. Adoby, I like the ReadyBoost idea. Will try it as soon as I buy a thumb drive. Mine currently is not acceptable according to Windows. |

The SSD really helps. A *lot*. While NAND flash is still an order of magnitude slower than RAM, it's a darned sight faster than HDD in terms of latency/random access. If you have a Core 2 Duo or newer CPU, chances are storage is a big bottleneck. I remember back when I was still waiting for consumer 1TB SSDs to be available. My older 1.3GHz C2D SU7300 ultraportable (with 256GB SSD) was more responsive than my new-back-then 2.7GHz i7-2620M laptop. Granted, the SU7300 could barely handle brute force 1080p H.264 decode. Certainly had trouble with Hulu back in the days pre-HW acceleration. |

I run a wide range of machines. My two most frequently used Windows machines both run Win10. I also run an recent iMac 27" Retina). These range from the iMac (Sierra, i7, SSD, 32gb RAM, external HDs totalling 20tb, ...) & Dell XPS (i7, fast HD, 8gb RAM, external HDs totalling 16tb, ...) to a Dell Venue 8 Pro tablet (~1.5ghz quad-core, 32gb eMMC, 2gb RAM, 64gb microSD). They all run calibre perfectly well, even the tablet where calibre is installed on the secondary drive (microSD card) and there are some 1800 ebook titles and over 3000 actual ebook files. Yes, the tablet it quite noticeably slower when converting or updated metadata, but its still quite serviceable. One the "big" machines, I generally have 2-3 large apps (Ps, Lr, Id, ...) and several smaller apps (email, browsers, ...) running all day. One the tablet I generally only run one app at a time, though occasionally run calibre, calibre's Editor, and a browser at the same time. Last edited by dwig; 02-15-2018 at 09:48 AM. |

How have you configured your swap disk? With just 4 gig of ram your system has to be doing a lot of swapping. How many books are in your Calibre library and how much disk space does it occupy? You may do better using an older version of Calibre. Just because it is older isn't a reason to discount it. The newer versions of Calibre use more resources. That makes sense. But the older versions are still supported or should I say forum supported. Find the most bulletproof version you can and "step back" to it. You will probably find it uses less resources. |

My PC has an i3 at 2.53Mhz I did add a 4GB USB for Readyboost. Also did a virus and malware scan. Cleaned cache/temp. Uninstalled many unused programs. Registry cleaner. Finally did a defrag. I noticed startup is faster. I'll see if performance improves. |

However, I discovered problems with Chrome. It looks like my user profile was corrupted after a recent update. Unresponsive. Reinstalled but it wouldn't start in normal mode. Uninstalled Chrome and installed Firefox. While Firefox uses lots of memory (lots!), my system has been running smoothly. Where do you find disk cache? |

Most OS dedicate a portion of RAM as disk cache. In addition otherwise unused RAM is used as disk cache. So to increase the disk cache you can reduce the number of programs taking up room running. Or add more RAM.
So "free memory" is a pretty good approximation of how large your disk cache is. In Windows it is also possible to use fast flash memory as disk cache, with the Ready Boost feature. Typically you only cache reads. It may improve performance significantly to also cache writes. Especially on a mechanical HDD. But if something bad™ happens before the write cache is flushed you may loose data or experience corrupt data on disk. |

My "free memory" according to WTM is 382MB. So far minimal slowdowns.
