Http Compression no longer working on FEDEMIS / MIEMIS servers
Issue #1172
closed
Am i missing something? Fiddler reports no compression on any javscript ot json file?? This has a big preformance impact on startup, and getting larger warehouse files.
this used to work??

I wonder if it is something to do with an upgrade to Windows or IIS?

I’m not entirely sure I am looking at this the right way. But It does seem like there is compression. See below from the Firefox Developers tools.
And looking at fiddler before clicking on decode.
It does still take this particular request (Exam dashboard, our largest) long to complete (~41 seconds on my current Internet) a transfer of just less then 1MB (compressed from 16MB). And it seems most or all the waiting is not in the transfer of the (compressed) response but in waiting for the server (presumably the SQL call). I highly doubt it takes 40 secs to compress 16MB of data on the server.

Interesting, because I don't see the encoding, and the same download is 17Mb, not encoded,…

Maybe check directly in the browser in Chrome or Firefox dev tools. Perhaps fiddler is automatically decoding the response and therefore you get the full size 17MB.

False alarm: caused by Fiddler setting 'Rules -> Remove all Encodings'

Is this only a server configuration? I did not personally change anything on the IIS configuration in production.
