| Summary | 0005743: gnunet-gns can be slow | ||||
| Description | As noted in 9f03df3be..777e57cfc, gnunet-gns can be excessively slow IF there are *thousands* of Egos in the identity service. The reason is that gnunet-gns iterates over all of them to do the longest prefix match. To do this iteration, we (1) copy all egos over to gnunet-gns via IPC, and (2) do an ECmul and hash operation per ego. That kills us. It would suffice (and be much, much faster) to integrate this longest-suffix-matching lookup into the IDENTITY-service API and then only return the one ego we care about. | ||||

Semi-offtop: how do peers end up serving thousands of identities? |
|
|
If you import a larger DNS zone, it may contain thousands of subdomains in the same zone (groupa.domain.com, groupb.domain.com). Each of these subdomains (that in DNS may be in the same zone) must have a new zone in GNS, as in GNS every "." is a zone-cut (unlike in DNS). So importing things like .se or .bfh.ch or .fr can give you thousands of egos. Or of course someone might suffer from a really bad case of multiple personality disorder ;-) |

This was fixed by extending the identity API. |
