I have a fairly recently built computer: i7-4790K CPU @ 4.00GHz, 32GB
RAM, GeForce GT 730, FreeBSD 10.4-BETA2.

On this computer, I have thunderbird-52.3.0_3, installed from ports.

Thunderbird takes 38 seconds to start up, that is, from clicking the
icon until Thunderbird offers a login prompt.

On the same computer, I also have Virtualbox + Win7 Pro installed. The
Win7 machine has 8 GB RAM. Thunderbird in the Win7 virtual machine
starts in 7 seconds.

In addition, Thunderbird in the FreeBSD host often freezes for several
seconds, as long as 20 seconds or longer.

During such "freezes" top(1) showed plenty of CPU and RAM being

As per instructions on page I

$ export MOZ_LOG=IMAPOFFLINE:5,MAILBOX:5,MSGDB:5,timestamp
$ export MOZ_LOG_FILE=/tmp/ztb_log

Just guessing that logging these modules might offer some clue.

Then started and shut down Thunderbird from the command
line. /tmp/ztb_log is created, but empty.

Please advise...
