I want to enable software compression on my chassis (stac, ascend, mppc). I think that if I enable it some users will get more download speed (when downloading not compressed information - like html sites).
Yes, they will. The downside (which is minor) is increased latency...gamers won't like it, but most users will prefer it.
What can affect ccp on my chassis and on client side?
Its a negotiated setting, so unless an implementation has a broken CCP implementation (which we've seen in the past), you won't have problems.
Does ccp take memory and/or cpu (if yes - how much)?
Yes, it will take cpu and a bit of memory. The Arc will not negotiate CCP if it decides it is getting cpu constrained, so you shouldn't need to worry about running out of cpu horsepower. The memory consumed is not terribly signficant, so as long as you're not already borderline on memory, you should be fine.
What compression is better?
My understanding is that stac is the best of those. Like I said, it is a negotiated value, so systems will negotiate a compatible protocol, or worst-case, drop back to no compression. -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456
