Playback takes long to start
Although I have good system requirements, I still have problems in the performance of Adobe Premiere Pro CS5. The rendering in the preview window (playback) takes long to start and hick-ups in video and audio appears. Jumping to some point in the timeline takes quite some time, sometimes 10 seconds.
Project
My project contains four MXF media files (sport event broadcasting), each about one hour long and 20GB in size. I also have imported some components from an After Effect project. All video an audio files already have peak files, located in the same directory as the original files.Configuration
Since I thought the current 4GB RAM was the bottleneck, yesterday I bought some extra RAM and now have 9GB working fine. Now my configuration of my Dell XPS 435MT is:- Processor: Intel Core i7 920 (2.66GHz, 8MB cache, 4.8GT/sec)
- RAM: 9216MB (3072MB (3×1024) 1067MHz DDR3 + 6144MB (3×2048) 1333MHz DDR3)
- Hard Drive: 750GB Serial ATA (7200RPM)
- Display : 21.5 inch S2209W European Black Widescreen Trans Value (1920×1080) DVI-D
- Graphics : 512MB ATI Radeon 4850 Graphics card
- Audio: Audio Integrated HDA 7.1 Dolby Digital capability
- OS: Windows 7 64-bit
In Premiere, the setup for Preference > Memory is at 6GB for Adobe and 3GB for other applications. First, the rendering looked good, but after some minutes the start of a preview takes longer again. Sometimes after quitting and restarting Premiere it goes well for some time.
When the previews took long to start, I started to look at some performance data. I’m not doing any other big processes, my CPU keeps running low and my RAM is quite constant at 4GB. So, that looks to be OK.
Can my hard drive be a problem? I have one hard drive, partitioned in two drives, where all programs are on C: and D: contains the project and all video and audio files (has about 60GB free space).
One small other thing I spotted was that the After Effects stuff is peak filed every time I open the project. For one specific component out of AE I already count 48 peak files. The other video files are not being peak filed again. Does Premiere make a new peak file for all imported components, although some components are untouched? I don’t think this is the cause, but it looks strange.
Are there other things to look at? Any help would be kindly appreciated.

You should have at least 2 drives in a editing system, one for apps and the second for data, having everything on one drive even if partitioned causes access problems due to housekeeping on the app partition.

The extra hard drive did the trick. All data are on a the new drive, all program + peak + cash on c:
Thanx for you tip. -
Unfortunately the problem returns. I’ve got all video on the new HDD. The peak files and program are on the other (old) HDD. Jumping to another part in the source causes delays, not always, but when it does, it takes some five seconds to start playing again. Or moving in the preview window forwards and backwards with the mouse a couple of times will freeze the image for five seconds. In the standard Windows Monitoring I don’t see any big load on the processor (2%) or RAM (3,5GB). If I restart Premiere Pro it goes well fore half an hour or so, then the problems are starting to come back again. Does anyore have any tip where to look at, any help is welcome again.
