Hi. We are rolling out the vanguard plugin for our users and wanted to understand some options we can enable.
* In many parts of the Security README setting *circ_max_megabytes* is recommended. Though it is discouraged for usecases involving Onionshare and Securedrop which we support. What is a reasonable limit to set? What happens is the max ceiling gets hit? Does it permanently disrupt the upload/download?
* "High load onion services may consider using 4 layer2 guards by changing the *num_layer2_guards* option in the configuration file https://github.com/mikeperry-tor/vanguards/blob/master/vanguards-example.conf, but going beyond that is not recommended." Does this benefit clients too? We would like to enable options that mimic the configuration used by actual high load onion services to provide them with more cover.
