Re: How can I set a maximum limit for gzip module?

April 30, 2017 10:12PM
Hi tokers,

I understand gzip-module that if buffers reach the limit, the module will wait some buffers are free.
I think there is a new question the resource (such like cpu and memory) will be over, when upstream contents are large size and lots of traffic.
I cannot set the limit of size of upstream contents. Because my nginx proxy is handling a lot of traffic from a third party.

My nginx server which turn off the gzip-module was so fine in almost two years. So I think there is no problem, but I am a little scared.
If I encounter this problem unfortunately, please ask you such like "Why dose't gzip-module have a max_length directive" again.

Thank you so much.
