Re: [tor-talk] Load Balancing/High Availability Hidden Services
-----BEGIN PGP SIGNED MESSAGE-----
I can talk all day about optimising and making a HS faster, but
nothing matches a DNS-round-robin pool for example in that respect.
Most optimisations you can make will be down to software you run and
splitting loads. So for example, if you have a high traffic site, you
can pan it out to 2-3 hidden services. So HS1 serves the general
requests, HS2 serves the static/cached content like images, and you
perhaps run the heavy downloads from HS3, so high load on any
particular one won't effect others and also split the web page loads
between several HS addresses and it won't be very noticeable to the user.
Use my XMPP (below in my signature) to get in touch if you want to
discuss in more detail. I have my own hidden service projects open
right now and in development to handle high loads so we can exchange
notes and release our info with others once we know what does and
doesn't work in each particular use case.
