Equipped with our very own commercially available SQL Solutions and proprietary software, our SQL Server database performance experts can help you diagnose and resolve existing and potential database performance problems, optimize your database code, and maintain best performance of your SQL Server database system.
While our
SQL Server Health Check
and
Comprehensive SQL Server Diagnostic Report
answer the Why’s and What’s of your database performance problems,
our SQL Server and Database Performance Optimization service
performs the How’s of your database system’s performance
optimization.
SQL Solutions follows a proven diagnostic and performance
optimization process that guarantees to solve problems and improve
performance of your SQL Server database system:
1. Profile and sample the database system’s activity
The
first step in the diagnostic process is to profile live database
activity using a proprietary database tool SQL Xray Recorder, our
commercially available database tool SQL Deadlock Detector, and the
SQL Server Profiler application. This is normally performed during
peak hours of heavy database load or when database performance
problems are frequently experienced.
Depending on the regularity or pattern of the performance
problem, database activity may be profiled and sampled more than
once, from as short as 15 minutes to as long as I hour in each
activity recording.
2.
Diagnose performance bottlenecks and offending execution calls
The resulting DTF (Deep Trace File) produced by SQL Xray Recorder is
then examined using SQL Xray Viewer, while the trace (.trc) file
produced by SQL Server Profiler undergoes analysis with SQL Trace
Analyzer.
At this point, bottlenecks in critical performance areas such
as CPU usage, I/O reads, I/O writes, logical reads, logical writes
and execution durations are examined and identified. On the other
hand, database execution calls responsible for and contributing to
the degradation of each performance counter are diagnosed and
determined.
3. Review database code, execution plans and table indexes
Based
on the diagnostic results gathered in the previous step, database
code for all poorly performing execution calls, their execution
plans, and indexes defined on (or lacking from) relevant
tables or views are
carefully inspected.
Specific lines or overall code are rewritten and optimized;
indexes are created or removed wherever necessary; poorly defined
covering indexes are modified, while index and table hints may even
be added to queries when needed.
Using SQL Xray Viewer and SQL Deadlock Detector, problematic
locks or deadlocks are also inspected for. When present, offending
code and contended objects are reviewed and the same optimization
steps as above are performed.
4. Test and benchmark optimized code (Before vs. After)
After the initial round of diagnostics and optimization is
performed, all altered and optimized code is fully tested.
Using SQL Server Profiler, traces containing profiled
database activity during the first step of the process are replayed
(at different times) on two different test databases – one
containing the original form and code of the production database,
while the other containing all modifications and optimization.
For each replay, database activity is profiled using SQL Xray
Recorder, SQL Deadlock Detector and SQL Server Profiler; DTF file is
examined using SQL Xray Viewer, and the resulting trace undergoes
analysis with SQL Trace Analyzer.
Performance results are then compared; SQL Deadlock Detector
logs are again examined to check whether problematic locks or
deadlocks persist. Steps 2 - 4 of the diagnostic and optimization
process are repeated until optimum performance gain is achieved.
5. Inspection of the database server's hardware specifications
Finally, in addition to the preceding steps performed, the
production database server's hardware specifications are assessed.
After completely performing and implementing database and
code optimization, Step 1 is again performed against the production
database server, followed by the diagnostics performed in Step 2.
When high CPU utilization remains to be experienced, an upgrade to
more powerful processors may be recommended or even required.
Persisting high I/O reads and writes may require an upgrade to a
larger amount of RAM to improve caching, or an upgrade to a more
powerful I/O subsystem. Implementing file groups or the proper RAID
level may also be recommended or required.
