HTTP optimisation
« on: January 22, 2015, 09:19:35 PM »
Could you please tell, is there any HTTP optimisation in wanos?
Maybe caching static files on datastore, or in RAM?
Or some kind of deduplication based on caching?

Dedup works on HTTP traffic, yes. Hence the data is kept in a combination of RAM and Disk.

We have also implemented a HTTP file caching feature that will be available for beta testing in a couple of weeks. Since there is overlap between dedup and file caching, not every case will see a perceivable difference. The object cache is useful though to keep some data out of the dedup datastore, which means the memory and disk space can be used for more new data and ultimately lead to a larger datastore of the repetitive data closer to the user and hence better performance in terms of reduction rates and throughput.

Thank you for the answer.
Looks great!
Which size of HDD partition do you advise for effectively cache and dedup 1 TB traffic per month?
Traffic - abstract usual HTTP surfing of home users.

It actually depends on the number of remote sites.

On the central sites 1GB Ram and 20GB disk (SSD preferred) for each remote site.

Once the HTTP cache goes live, about 100GB on the branches (pending final specs)

For now we have only one remote site with 5 mbit/s link.
Ok, thank you, we'll start with this size.
