We have been experiencing slow transfer rates from our Siemens MRI consoles to storescp (DCMTK 3.6.6).
After reading "FAQ #48: Slow transfer when sending many small DICOM images", I tried the following suggestion:
Code: Select all
export TCP_NODELAY=1
I am just wondering about this sentence:
What do you mean by "modern operating systems"? Which operating system is relevant? The OS of the MRI consoles? The OS of the server running storescp?Starting with DCMTK 3.6.2, the Nagle algorithm is not disabled by default since this does not seem to be appropriate (anymore) for most modern operating systems.
In our case:
- the server runs CentOS 6.5 (yes, I know, we need to update it ),
- the consoles of the 3 T Siemens Prisma Fit run syngo MR E11 on Windows 7,
- the consoles of the 7 T Siemens MRI run syngo MR B17 on Windows XP.
