Improve - speed up Outlook connector KOFF
Recent Beta 3 of Kerio Connect 7.4.0 contains many improvements in KOFF performance and lowers memory consumption.
If you want to participate in beta-testing this feature and the product, please submit a betatesting request on:
Please share your feedback!
We plan to still work on improving KOFF performance in future versions.

We are currently looking at ways to provide performance improvements that should benefit all Kerio Connect users.

In my opinion the only way is to switch to a SSD. Compare KOFF Firebird database of let's say 10-20 GB size with a PST/OST of the same size and you end up needing SSD anyway. During the last years the SSD size grew and prices dropped significantly, so for a heavy worker that is the way to go now.

What's the status on this 3-year project?

I can support this. KOFF is REALLY slow with bigger mailboxes, especially for roadworkers with laptops and 5.4k drives. Not everyone runs SSD's.
Please investigate in the OutlookOfflineConnector. Ist sooooooo slow. Espeacialy Changing beween clander and mail view, or searches in emailfolder with a few thousand mails. Exchange PST or OST are much faster. If KOFF Needs more RAM to be fast, OK! Most PC have plenty of RAM.
I really push my customers to choose Kerio vs. Exchange, but now I'm in serious troubles because ALL of my customers are complaining about Outlook (with KOFF) being TOO MUCH SLOW.
The only improvement that has happened here is relying on customers to purchase fast SSDs... I see no improvement to this issue for 3 years
The only improvement that has happened here is relying on customers to purchase fast SSDs... I see no improvement to this issue for 2 years
Searchspeed and Startup in Outlook with KOFF is a drama.

Any comments on this ?

How is the performance improvement going? Because the last update dates back 2+ years...
Synchronization has gotten faster but search speed is awful (8.3.2).
C. Spann commented
20 users consuming about 120 GB on Windows Terminal Servers just for caching mails that already are online on kerio server! Please STOP that.!
... also the receiving of messages after 2 weeks of holiday, takes a while and there is no window, no sign, no send/revice-status in outlook.
For users: it looks like, it doesn't work

Please keep this up! We like Kerio but it's too slow on outlook - WAY too slow (we are on 7.4.2). we have many users with >1G, probably 25+ (all the senior management) with 10G+.

@administrador: That's not true. It is not the account size but sometimes the folder size that matters.
i don't understand why PST is so much faster while KOFF is using a database. Maybe there is a way to build KOFF so it uses pst as a storage?
More than 500Mb account? Forget KOFF you can sleep while you wait!
Dee Lowndes commented
Speed of this has to be improved windows users are used to fast access to there email and searching no matter how they manage there mailboxes. It should be planned and started already as the potential market once sorted is huge for you. As it is we struggle to suggest it to the majority of our clients because the way they work just doesn't suit the speed of the product. If I could give 9 votes to this I would!
Flat file appears to be the issue so perhaps you should move it to a DB solution and eliminate that problem?

Speeding up + supporting Terminal Server please
It's much better now in 7.2.0 but it stills reads/writes humongous amounts of I/O on startup.
