got it -- what "blocking time" mean in this context.
per http://gtmetrix.com/parallelize-downloads-across-hostnames.html
the blocking due to limited number of connections between browser and web server.
at web server's side, please check settings of
lsws web admin->Server->Security->Per Client Throttling

when there is ddos, have to reduce those values to mitigate ddos.
however during normal time, set too small will affect site's performance which you've reported in this thread.

GTmetrix gathers data from both Google PageSpeed and YSlow at same time, so we're using it more often than Google's alternative.On the other hand, Google PageSpeed offers neat features like download optimized images, scripts and CSS (which GTmetrix don't), so it could be a better option if you (or your client) need that.
