I'm working on PageReader per queue these days. Unluckily some problem was encountered. After investigation, I found it was related to #2740 which would sync files while closing. Given we put PageReader in PageSubscription meaning 100 times of file open/close for each page in our case(100 queues), although page file is only opened for reading, the sync operation does cause great performance loss - ~5000 msg/s received and 13000 msg/s sent now compared with 16000 msg/s received and 11000 msg/s sent of pr. Should I file a new jira and pr to fix the problem introuduced by #2740 or just fix it in this one?
