For those of you on the latest Lightroom CC you might be experiencing some problems with memory leaks. I'm still on LR 5 so haven't experienced this in person, but posting as it might help others.
Adobe's aware and will release a fix but in the interim if you rename your Lightroom video cache directory (e.g. to video.old) and restart Lightroom you should find it stops leaking RAM - it'll create a new folder in there.
Location is .. C:\Users\USER\AppData\Local\Adobe\Lightroom\Caches\Video

Cheers
 
I'm intrigued. What is and how does a RAM memory leak occur? I'm interested because I've had so many problems with LR CC updates that I've decided to abandon it altogether and go back to LR5. Is this only about video?
 
From what I've read, the memory leak is when importing, so simply creating a new file loses your previous cache, throwing away previous info. I'm assuming by this the video cache is growing large.

Caching in Lightroom and performance issues have been well known about over a number of versions. Is it suddenly worse with a recent version?
i.e. http://www.lightroomfanatic.com/tutorials/advanced/why-and-how-to-clear-your-lightroom-cache/

Why not move the video cache away from the system drive, or limit the size?
 
I don't think it's just on import or just with video.

It looks like it just leaks - consumes more and more memory resources until Windows offers to kill it a few days later. Huge number of handles and using massive amount of working set RAM.
This is on current version on CC.

If you're not seeing the problem then I'd suggest not worrying about it - if you use it for short periods and close it out it's unlikely you'll see this.
 
Thanks for the headsup (y)

Can't say, I've encountered this issue, but I've developed a habit, of restarting LR on a regular basis.

About time, Adobe bit the bullet and do whatever is necessary, to eradicate the speed issues, etc. LR is an excellent program but it can become, very annoying, when used for any length of time, due to speed issues, etc. I'll not even start about the import speed :eek:

I'm a Lightroom 6 standalone user, don't have issues with the import speed, unless my hardware is masking issues. I use a usb 3 card reader, importing to a SSD just for this years raw files. Lightroom cache and catalogue are on another ssd, with the OS and program on a third. Any data, previous years raws, completed and exported jpegs etc go onto a large internal raid. Using SSD's for cache/catalogue and raw imports has a significant improvement in speed.
At least they've now taken out the import wizard/my first import.

Since lightroom 4 though, there's always a slight delay switching to the develop module first time.
