It would probably be a noticeable difference though. Similar to the differences between HTTP vs HTTPS.
Of the additional load generated, half would be in the transitioner while it is generating replicas. When the transitioner slows down, it slows down all the other daemons. ----- Rom -----Original Message----- From: boinc_dev [mailto:boinc_dev-boun...@ssl.berkeley.edu] On Behalf Of David Anderson Sent: Tuesday, November 17, 2015 12:57 PM To: boinc_dev@ssl.berkeley.edu Subject: Re: [boinc_dev] 153f66: Server (assimilator): add random string to result ... You're right - enabling upload certificates (which work, AFAIK) would fix the problem too, as long as the project's upload directory isn't accessible. If I recall, we made upload certificates not the default at a point where S@h's servers were overloaded and we were looking for every performance boost (actually the impact is probably negligible). -- D On 11/17/2015 4:04 AM, Christian Beer wrote: > On 17.11.2015 12:24, Nicolás Alvarez wrote: >> 4.
