System Performance and Preparation (“Success is in the details”) The more RAM you have; the better. With today's memory prices you might want to optimize your current memory system. Video Editing (VE) users should have at least 128 MB RAM to get decent performance in Win ME. My test have shown that Premiere 6.0 responds much better with at least 384 MB of RAM but 128 MB (with proper tweaks) is achievable and effective in RealTime. The latest DirectX 8.0a and 8.0bda patch were used and very responsive / stable. Before doing any significant a number of “tweaks” it is advisable (and actually beneficial to performance success) to do a number of preparatory items. This places the OS in a more responsive- receptive mode for “tweaking”. Do a disk scan and repair to clear up bad sectors. Do a disk defrag to compact and un-fragment data. Scan registry for fragments and compact (compress). To do this safely and effectively programs such as SystemSuite or Easy Cleaner or Norton Utilities. They are much better than tools in Windows. Compressing removes any unused space, making the registry file smaller & faster. The “TWEAKS” Virtual memory – Windows uses a dynamic virtual memory manager to handle Swapfile duties. It provides more memory to applications than is physically present in the computer RAM (It uses hard disk space to simulate RAM). The amount of RAM in the computer plus the size of the “Swapfile” equals the total virtual memory size. Windows uses a dynamic Swapfile that remains at a size of 0K until it is needed. The Swapfile can grow to use all the available space on the hard disk if it is necessary. This is the default setting for the “swapfile”. With Video Editing it is more efficient to set this yourself rather than let Windows dynamically manage it. When Win manages the file it can increase or shrink and eventually gets distributed (fragmented) over the disk taking more time to access. Calculating Virtual memory - Before you can set your Virtual memory you’ll want to calculate what to set it too. Some recommend using a general formula - Physical RAM X 2. This can, however, be incorrect. Using that formula, a person with 64 MB RAM should set 128MB, while a person with 128MB RAM should set 256MB. Clearly the person with little RAM needs a greater amount of Virtual memory than the person with a lot of RAM. I suggest RAM X 2.5 for systems with 256 MB or less and RAM X 2 for those above 256 MB. Selecting a fixed minimum swapfile will drastically reduce the thrashing your hard disk that it takes from 98/ME's “dynapage” 1. Right click on My computer & select Properties. Select the Performance tab. 2. Select Virtual memory. Choose Let me specify my own virtual memory setting. Set it as shown below (substituting in your own values of course). The values shown below are for a system with 512 MB of physical RAM. Once you have set your Virtual memory size you can further optimize it. The Swapfile is best placed on the outer edge of the hard disk it is located on. Windows 9x\Me Disk Defragmenter will not do this. You’ll need a disk defragmenter like Norton Speed Disk or McAfee Nut’s & Bolts to do so. I do not recommended that you put your Swapfile onto a separate partition of your system drive as this will increase the time to access it & increases hard drive head movement as well. Instead, it is recommended that it be placed on the most used partition of the least used drive. This will mean the C:\ drive where Windows is installed for users with a single hard drive. If you have another hard drive installed you should use that instead. To change where the Swapfile is located, change the Hard disk location when setting Virtual memory (see display above). Do not place the swap file on your video disk as high editing and capture activity can cause conflicts / delays. Ideally you would want to place your Swapfile onto a separate hard drive, on a separate IDE channel (if possible do not put 2 high activity hard drives on the same IDE channel). I currently have mine on the system drive. Again, the swapfile should go onto the outer edge of that hard drive using a Utility Program like Norton or Nut’s & Bolts, etc
Right click on My Computer, select Properties. Select the Performance tab. Now hit the File system button. Go to the Troubleshooting tab. Disable new file sharing & locking semantics. This setting controls file-locking mechanisms in Windows. Tick (Disabled) this setting if you are currently experiencing problems with certain programs. However, it should be used as a last resort - your system will perform optimally with this setting “Unticked” (Enabled). Disable write-behind caching for all drives. This setting tells the computer to cache all disk writing operations to that particular drive. Basically, this means that a certain amount of what is being written to the disk is actually being stored in the RAM and isn't written to the disk until either the cache starts overflowing (in which case it starts writing from the bottom of the cache) or the computer is shut down. Enabling this setting generally increases performance but in intensive editing mode and real-time operation RAM can become overloaded and also fragmented to actually reduce performance. Leave it ticked (disable write-behind) unless have large amounts of RAM and then even do high use (intensive editing test) to verify effectiveness. Disable System Restore (Windows Millennium only). Ticking this setting will semi-disable Windows ME’s system restore capability. It is (semi) in it still replaces/rebuilds some files, e.g. autoexec.bat. The benefit of Ticking this setting is that it will lessen the amount of hard drive activity used to build System Restore files. This will improve editing system performance significantly. 3.) Vcache By default Windows will determine these settings based on RAM installed (the Min/MaxFileCache). With Video Editing is better to set Vcache settings yourself. Vcache is limited to a maximum cache size of 800 MB – this really shouldn’t matter to anyone but those with excessive amounts of RAM (Greater than 512MB). On such high RAM systems not limiting the Vcache has been known to cause problems). Click on Start, Run. Type in system.ini & hit Enter. Scroll down to the [vcache] section.
