Without knowing anything about your setup let me chuck a few stones

If relstorage is growing for blob uploads, I would think something is

Yes, that seems like a plaster on top of a broken bone.

This sounds dangerous to me ..

Configure caching such that client/CDN/varnish/nginx keeps all the big
files that they should.
Use collective.xsendfile to make file requests go directly to the
front-end server (but note "Blob handling in ZODB is very effective
already (async sockets, just like Apache or nginx would do ). [...]
This add-on only removes the need to proxy the file data over socket
for a lot of good tips.
