hellion Posted November 15, 2018 Share #26 Posted November 15, 2018 (edited) I would not want to disturb you but... dd without direct option shows only cache speed - no more. In some configurations, you can get a linear speed without a cache higher than with a cache. In some you will receive hundreds of megabytes per second, with linear performance in units of megabytes. With the direct option (iflag = direct for reading, oflag = direct for writing), dd checks only the linear velocity. Which is absolutely not equal to the maximum speed (if we are talking about a raid on many disks, then a raid in several threads can give more speed than in one), not a real performance. link1 link2 So for correct measurement, we need to do a drop cache before testing.

ttan98 Posted July 16, 2019 Share #36 Posted July 16, 2019 Hi Fellows, I am new here however I have installed 2 systems one based on 1.02b mod loader using 3615XS,V6.17and another 1.04b loader using DS918+ V6.2.2 using i3 3470 and AMD A12-9800 respectively. Both systems work fine. I am not sure what software you guys use to test the system's performance, please direct me and/or name the Syn. pkg used or using an external s/w pkgs used. A simple direction on how to use it would help, Thanks. Quote Link to comment Share on other sites More sharing options...

ttan98 Posted July 18, 2019 Share #40 Posted July 18, 2019 My contributions: System 1 i5-3470 using 1.02b mod loader emulating DS3615XS using DSM 6.1.7 CPU:582 Mb/s System 2 AMD A12-9800 using 1.04b loader emulating DS918+ using DSM 6.2.2 CPU:633 Mb/s The performance of both CPUs are comparable. I didn't test the HDD cos it depends on the type and made/brand of the hard drives. From assessing the results above, the CPU performance does not really improve that much if you use i3 to i5. Celeron J3XXX or j1XXX is clearly inferior and the performance is about 1/2 of i3 or i5. Quote Link to comment Share on other sites More sharing options...
