php slow log? How fix flushOutput()?

[pullvideos]

Hi,
my server recorded php slow request log:
script_filename = /public/file_download.php
[0x00007ffecc32f818] flushOutput() /public/includes/functions.inc.php:2131
[0x00007ffecc32c380] flushOutput() /public/includes/class.file.php:397
[0x00007ffecc3294b0] download() /public/file_download.php:61

What is flushOutput?Anyone know how fix it?
Thank you!

It's used to send the downloads via PHP. The next version of the script (due any day!) will provide the option to bypass PHP and use XFileAccel on NGINX or X-Sendfile on Apache. This will clear the issue.

Thanks for your quick support!
My site is running on version 3.5.3.The option is in version 4 beta? How upgrade v3.5.3 to v4?
My site is configed NGINX and Apache working together so I will config XFileAccel on NGINX or X-Sendfile on Apache?
Thanks!

Yes it's in v4 beta. Other info about upgrading here:

It depends how you have your setup configured. Whichever is serving PHP requests you should set for XFileAccel/X-Sendfile.
