Hi All,
Ryan Lane and I are migrating gerrit's db to a server in eqiad (where the gerrit app server is located) on Friday, and have a downtime window of 18:00-19:00 UTC (11am-12pm PDT). Actual downtime should be shorter. Gerrit makes many mysql queries for some page requests; this will improve the latency of such pages. Additionally, the new db will have both slow and sample based query profiling in ishmael which should assist with further optimizations.
