Verbiage: Compression tradeoffs: time space CPU

Chacham (981) writes | more than 4 years ago

User Journal 3

Compression used to give up time for space. Faster CPUs have made it giving of CPU time for time and space. At least in this example.

yes, a very interesting observation (1)

That CPU's have become so fast, compression no longer means trading an undesirable change in time for a desirable change in space, but trading an undesirable change in CPU utilization for desirable changes in both time and space. We've/we're successfully shifting the downside to something much less tangible to us.

Time to bring back doublespace, or what those "doubling" hard drive compression drivers we're called. :)

NetWare still has compressed volumes, if you want them. It's still a bad idea.

However, the fast CPUs do make "stored in encrypted form" reasonable. GroupWise has been doing this since version 1. I expect MS Exchange will catch up in the next version or so. (That I recall, they tried it once, but it didn't work with MS Office....)
