DisplayLink Causing my Machine to run very slowly

[JamesGuymer]

Hi

Im running Yosemite, Parallels with a MacBook Pro 2.6Ghz 16Gb, with 6 external monitors 2 off the macbook and 4 with the StarTech uSB32DVIPro

I primarily use this as a development environment.

Recently I've noticed a massive slowdown in performance, even as far as Typing code. Ive gone through a lot of Mac Checks, reset permissions etc and have installed a fresh version of windows ruling out any other issues.

Yesterday i removed the DisplayLink drivers and the performance was considerably faster. (i appreciate it was only 2 monitors but it was fast). I reinstalled the your drivers 2.4b and it slowed again.

i ran sudo opensnoop after reading another thread and im seeing the following:

Ive attached my display link information for you

Ive had to remove your drivers for now and revert to 2 monitors which is not ideal for what im doing.

Thanks
