The max_mpx setting is set separately per vFiler. The setting in vfiler0 does not affect non-default vfilers.

cifs.max_mpx
This option controls how many simultaneous operations the filer reports that it can process. An "operation" is each I/O the client believes is pending on the filer including outstanding change notify operations. Clients such as Windows Terminal Server or IIS may require that this number be increased to avoid errors and performance delays.
CAUTION - The approved values for this parameter are 50, 126, 253, and 1124. The most accurate way to determine which number to use is to measure the Redirector-Current Commands statistic on the client with NT perfmon and to increase the number until Current Commands does not hit the negotiated limit. For more information see Microsoft Knowledge Base articles Q191370 and Q232890.
CAUTION - This number should only be changed while cifs is terminated.
CAUTION - Only use the approved values to avoid Q232890.
CAUTION - This value affects allocations in the clients. Use the smallest value necessary for correct behavior.
Default: 50
Values: 50, 126, 253, 1124
Effective: Immediately
Persistence: Remains in effect across system reboots
VFILER CONSIDERATIONS
Each vfiler has its own set of options. Vfilers, however, recognize only a subset of the options recognized by a filer. The list of options recognized by a vfiler are:

These options only affect the operation of the concerned vfiler. When run in the context of a vfiler, (e.g. via the vfiler run command), the options command only prints the options recognized by a vfiler, and can only change these options.
