BTW, is 3.22 also affected by this?
Yes but to a lesser extent, bug 16044 has not been backported (yet?): in 3.22, CGI->new is overridden to call clear_syspref_L1_cache.
AFAIRC feching a syspref from memcached takes 80-120 usec on average, in 3.22 there are ~1500 ->preference() calls per catalog search (for 20 results per page, ~3000 for 50 results per page). There is still some (hard to say how much) syspref caching going on.. Worst case scenario: 1500 * 0.0001 = 150 msec penalty. Unless someone is running 3.22 under plack without memcached (worst case: 1500 * 0.0014 = 2.1 seconds) - probably not such a big deal. -- You are receiving this mail because: You are watching all bug changes.
