Exchange 2013 - All of a sudden OWA attachments are very slow to upload or download
All of a sudden when using OWA/Exchange 2013 it takes forever to upload or download attachments. We did have a memory issue but I just doubled that. Now cpu utilization is at ~25-50% and RAM is at 50% w/ 24GB.
MB server: EXCH2013/CU8, 4 cpus, 24GB RAM, 600GB Database partition/95GB free disk space
We have 627 mailboxes on one MB server. Four of our five d/b's are ~115GBs, the fifth is 55GB.
Speedtests confirm full 50MB bandwidth up and down. No firewall changes. No new s/w installed. All I did do a lot the day before this issue arose was use the Exchange Shell a lot to delete emails in user's recoverable items folder--to free up space. I've done this a lot before with no issue.
No memory issues. Lot of memory. Lots of cpu util available.
Any ideas? Could the CAS or Edge server be causing this?

EXCH2013/CU8
Lets start right there.
Any reason you are so out of date? To be in a supported configuration you need to be on the latest, or the previous CU. You are 12 months out of date.
I would suggest installing the latest CU, 12, which was released yesterday. 11 introduced some issues which can cause problems for some admins, so you might want to skip that.
I would also say that for that number of users I would be having at least two, preferably three multi-role servers in a DAG. Single server with that number of users would be a concern.

Because no other comment was even close to the solution AND I figured it out entirely on my own. Not even by searching other EE Q&A's.
Did you tried rebooting the exchange after adding memory?
Was the time sync is proper between your CAS/Edge and Exchange MBX?
How the users are connecting only OWA? It could be also browser issue too.
How many users are affected?
