Hi Ashley,
The read and write speed is what we are using to provide a specific, measurable bench mark. In actual fact the user experiences the slow down across the machine, including but not limited to, start-up, opening file explorer, navigating between folders, opening applications, opening files, coping files. If we ship a new laptop already encryption the user doesn't know any different. However if we ship them something new and encrypt once they have started using it, this is when they notice the difference and complain. If we onboard new customers and push out encryption, we get many complaints that our systems and ESET has adversely affected their computers.
We have noticed these affects over all manor of devices and drives. We see it on Dell Laptops with hi-speed NVME using RAID, and using ACHI. We see it on Lenovo laptops with old hard drives and new SSD's. The age and drive performance will dictate the extent of the slow down - however the slow down is always present to some extent.
Our primary comparison is EFDE vs BitLocker vs No Encryption. For the most part we are not including EEE as it has been our intention to migrate the reaming clients to EFDE so we can utilize a single pane of glass for management (ESET Protect on-prem).
If customers perceive bitlocker to be faster, cheaper and deliver the same grade encryption, it places us in a difficult position as to why we are still using ESET Encryption.
Is this an issue that ESET acknowledges and is there some commitment to improving?
or
Is this an issue with "Software Encryption" and it is what it is!
The answer makes quite a big difference to us. If I am to commit time and resources in setting up test machines, test hardware and reporting differences between EFDE vs BitLocker vs No Encryption, I would need some assurance that ESET would be taking that information with a quest to improve the product.
If there isn't a commitment, and our efforts are not going to contribute to change, then I'd rather not lose the resource time. We would need to learn to live in the "It is what it is" world.
To what degree have other partners found the slow down across their IT estates?
Best wishes,
We have been using ESET for over 10 years, and adopted Deslock when it was first introduced to the ESET ecosystem. Over the years we have noticed Encryption adversely affecting system performance - primarily in the read and write speeds. With some hard drives, this has been up to a 70% drop in speed. We see this on SSD's and NVMEs'. By upgrading a faster drive get and improvement, but once you decrypt it, you realise just how fast it could have been.
ESET technical support are getting us to setup test cases, logs and examples to prove this. We have seen this across many clients, many workstations and disk drives.
Is this performance draining something other ESET partners have noticed?
Is this hit to performance something that we have to live with if we want ESET Encryption?
Does ESET even recognize this is an issue - or is it just us?
PAACIT-Richard received kudos from Andras Kovacs in EFDE and EEE both slow down the disk speed dramatically.
