Some settings to help optimize your Question2Answer site's performance.
If QA_HTML_COMPRESSION is true, HTML web pages will be output using Gzip compression, if
the user's browser indicates this is supported. This will increase the performance of your
site, but may make debugging harder if PHP does not complete execution.
QA_MAX_LIMIT_START is the maximum start parameter that can be requested, for paging through
long lists of questions, etc... As the start parameter gets higher, queries tend to get
slower, since MySQL must examine more information. Very high start numbers are usually only
requested by search engine robots anyway.
If a word is used QA_IGNORED_WORDS_FREQ times or more in a particular way, it is ignored
when searching or finding related questions. This saves time by ignoring words which are so
common that they are probably not worth matching on.
Set QA_ALLOW_UNINDEXED_QUERIES to true if you don't mind running some database queries which
are not indexed efficiently. For example, this will enable browsing unanswered questions per
category. If your database becomes large, these queries could become costly.
......@@ -146,15 +146,15 @@
Set QA_OPTIMIZE_LOCAL_DB to true if your web server and MySQL are running on the same box.
When viewing a page on your site, this will use many simple MySQL queries instead of fewer
complex ones, which makes sense since there is no latency for localhost access.
Set QA_OPTIMIZE_DISTANT_DB to true if your web server and MySQL are far enough apart to
create significant latency. This will minimize the number of database queries as much as
is possible, even at the cost of significant additional processing at each end.
Set QA_PERSISTENT_CONN_DB to true to use persistent database connections. Only use this if
you are absolutely sure it is a good idea under your setup - generally it is not.
For more information: http://www.php.net/manual/en/features.persistent-connections.php
Set QA_DEBUG_PERFORMANCE to true to show detailed performance profiling information at the
bottom of every Question2Answer page.

background to manage the queuing and transport of these messages from publishers (event streams) to subscribers
(users' lists of news updates). While we could have a cron-style process to manage this, I'm avoiding it for as long
as possible since it complicates setup. It also means there can be delays in updating users' news feeds.
So instead we adopt a hybrid approach. For each event created in an entity's stream, we record a single copy of that
event in the entity's stream in the qa_sharedevents table. In addition, by default, we place a copy of that event into
the list of news updates for each user subscribed to the stream, via the qa_userevents table.
However, if there are more than a certain number of subscribers to the stream, we skip this second step, i.e. we
only record one copy in the qa_sharedevents table. This limits the cost of publishing an event.

Note that this approach isn't aimed at reducing the total cost of keeping all users up-to-date on all events, but
rather ensuring that no individual operation (posting an event or retrieving a user's list of updates) takes too
long, since that would turn into a very slow response time for the corresponding HTTP request.
What should we use for the threshold T, so that if a stream has more than T subscribers, its events are only
recorded in the shared stream? One approach is as follows:
