GB RAM. Im using that extra memory not available to XP for a ramdisk. I use a product called VSuite Ramdisk, from an outfit called Romex Software. VSuite is available in several different versions. The Free version does all I require. VSuite Ramdisk is here. When its active, XP sees 7. MB of RAM beyond the 3. GB or so XP can access directly as a compressed NTFS volume identified as drive Z Im testing beta versions of Mozilla Firefox, Sea. Monkey, and Thunderbird, and I run those from the ramdisk. The stuff run from the ramdisk is stored as zip archives on the hard drive. I wrote batch files to unzip them to the ramdisk, and to update the zip files on the hard drive after any changes have been applied, which happens daily for things like nightly builds. It proved faster to unzip from and zip to archives than to simply copy the files from the HD to the ramdisk and vice versa. I run XP Pro, which includes Group Policy Editor, and I used it to associate the batch files as logon and logoff scripts. The ramdisk is populated automatically when I boot up and log on, and changes are stored back to the HD when I log off, shutdown, or restart. It works quite well, and when Firefox is run from a ramdrive, and its profile is also on a ramdrive, things are gratifyingly quick. On my machine, Firefox 567 invoke in about 4 seconds with 8. The more extensi. FF takes, as it must enumerate and instantiate each installed addon. With no extensions loaded, Id expect startup times on the order of two seconds. I also have Firefox set to store its disk cache on the ramdisk, outside of the profile, and do this routinely for any version, whether run from the HD or the ramdisk. Its a quick speedup. I do something similar under Linux by telling Firefox to put cache in devshm. This is POSIX shared memory, and exists in RAM or swap, but not in the file system. Dennis.
